Prime Numbers
A prime number is a number that has exactly two factors: 1 and itself. All whole numbers greater than 1 are either prime numbers or can be written as the product of prime numbers. There are an infinite number of prime numbers, but they occur less frequently among larger numbers. Prime numbers are important in cryptography and number theory.

What are the three different prime number that divide exactly into 2233?
Oh, what a happy little math question! Let's see, the three different prime numbers that divide exactly into 2233 are 29, 3, and 7. Each of these numbers can go into 2233 without leaving any remainders, just like painting a beautiful landscape with different colors blending together harmoniously.
109 can be represented as the sum of two prime numbers, specifically 53 and 56. It is also the cube of 5 plus the square of 4, or (5^3 + 4^2). Additionally, 109 is a prime number itself, meaning it is only divisible by 1 and itself.
What prime numbers are between 6 and 10?
The prime numbers between 6 and 10 are 7. Prime numbers are integers greater than 1 that have no divisors other than 1 and themselves. In this case, 7 is the only prime number within the specified range.
Which of these numbers is not a prime number 29 39 and 19?
Well, honey, 39 is the odd one out in this lineup. 29 and 19 are both prime numbers, but 39 is a composite number because it can be divided by 3 and 13. So, if you're looking for a prime number to hang out with, 39 is not the one to call.
What number between 120 and 130 is divisible by 3 and has a digit sum divisible by 4?
To find a number between 120 and 130 that is divisible by 3 and has a digit sum divisible by 4, we first consider the numbers in that range: 121, 122, 123, 124, 125, 126, 127, 128, 129. Next, we calculate the digit sum of each number: 121 (1+2+1=4), 122 (1+2+2=5), 123 (1+2+3=6), 124 (1+2+4=7), 125 (1+2+5=8), 126 (1+2+6=9), 127 (1+2+7=10), 128 (1+2+8=11), 129 (1+2+9=12). Therefore, the number between 120 and 130 that is divisible by 3 and has a digit sum divisible by 4 is 123.
What is it called when a number can only be divided by one and itself?
A number that can only be divided by one and itself is called a prime number. Prime numbers are integers greater than one that have no positive divisors other than one and themselves. Examples of prime numbers include 2, 3, 5, 7, 11, and so on.
What are the prime numbers between 40 and 60?
The prime numbers between 40 and 60 are 41, 43, 47, 53 and 59.
What is the prime of numbers 21 22 23 24 25 26 27 28 29 30 and why?
The prime numbers among the given list are 23 and 29. A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. In this case, 23 and 29 have no divisors other than 1 and the numbers themselves, making them prime. The other numbers in the list have divisors other than 1 and themselves, so they are not prime.
What number from 1 to 25 has the most factors?
Well, honey, the number 12 takes the crown in this factor frenzy. It has a whopping 6 factors: 1, 2, 3, 4, 6, and 12. So, if you're looking for the popular kid on the block in terms of factors, 12 is your go-to choice.
NO!!!!
By the very fact that it ends in '5' , means that it is a compound number (multiple) of '5'.
What is dxxxviii in Roman Numerals?
DXXXVIII in Roman numerals is equivalent to 538. In Roman numerals, D represents 500, X represents 10, and V represents 5. The smaller numerals are added to the right of the larger numerals, except in cases where a smaller numeral appears before a larger one, in which case it is subtracted.
How Express 840 as the product of prime numbers?
Oh, what a happy little question! Let's break down the number 840 into its prime factors. We start by dividing 840 by the smallest prime number, which is 2. Repeat this process until you cannot divide anymore, and you'll find that 840 can be expressed as 2 x 2 x 2 x 3 x 5 x 7. Just like that, you've decomposed 840 into its prime factors, creating a beautiful mathematical masterpiece!
Which is greater0.01 or 0.010?
They are equal to each other.
Answer:
It is a question of whether the numbers have been truncated or rounded and the precision of the data. Assuming both numbers are handled in a similar fashion in any one case:
- If absolutely precise 0.01 is 0.01 followed by any number of zeros and 0.010 is 0.010 followed by any number of zeros. So the numbers are the same
- If truncated 0.01 can be any number up to just less than 0.02 and 0.010 can be any number up to slightly less than 0.011. So 0.01 is potentially larger
- If rounded 0.01 can be any number over 0.005 up to just less than 0.015 and 0.010 can be any number over 0.095 up to slightly less than 0.0105. So 0.01 is potentially larger or smaller than 0.010.
What is the composite number between 60 and 80?
Oh, what a happy little question! Let's take a moment to appreciate the beauty of numbers. The composite number between 60 and 80 is 64. It's made up of factors other than just 1 and itself, like 2, 4, 8, 16, and 32. Just like in painting, numbers can come together to create something truly wonderful.
The number 143 is divisible by what number?
The number 143 is divisible by 11. This can be determined by performing the division operation 143 ÷ 11, which results in a quotient of 13 with no remainder. Therefore, 11 is a factor of 143, making it divisible by 11.
The numbers between 20 and 40 are 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, and 39. These numbers form a consecutive sequence with a common difference of 1. Mathematically, this can be represented as {x | 20 < x < 40}.
What are the multiples of 6 and 15?
The multiples of 6 are numbers that can be divided evenly by 6, such as 6, 12, 18, 24, and so on. The multiples of 15 are numbers that can be divided evenly by 15, such as 15, 30, 45, 60, and so forth. The least common multiple of 6 and 15 is the smallest number that is a multiple of both 6 and 15, which is 30.
What is the smallest 6 digit prime number?
Oh, what a happy little question! The smallest 6-digit prime number is 100003. Just imagine that number as a tiny tree in a vast forest of numbers, standing tall and unique in its own special way. Remember, every number is special and has its own beauty.
What 2 digit number with 10 factors?
Oh, dude, you're hitting me with the math questions, huh? So, a 2-digit number with 10 factors would be 60. Why? Because it has factors 1, 2, 3, 4, 5, 6, 10, 12, 15, and 30. Boom, math wizardry at its finest!
Is prime factorization an NP-complete problem?
Yes, prime factorization is not an NP-complete problem. It is in fact in the complexity class NP, but it is not known to be NP-complete.
