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 is 2x2x3x5x7?

The product of 2, 2, 3, 5, and 7 is calculated as follows: 2 x 2 = 4, then 4 x 3 = 12, next 12 x 5 = 60, and finally 60 x 7 = 420. Therefore, 2 x 2 x 3 x 5 x 7 equals 420.

What is 441 as a product of its prime factors?

7)441

7)63

3)9

3)9

3)3 = 1

Hence 441 is the product of 7x7x3x3 = 7^(2) x 3^(2) = (7 x3)^(2) = 21^(2)

Is 5882353 prime?

No, 5,882,353 is not a prime number. It can be divided evenly by 7, as 5,882,353 ÷ 7 = 840,379. Since it has divisors other than 1 and itself, it is classified as a composite number.

How do you write x(x-2) 3(2-x) as a product of binomial?

To write ( x(x-2) + 3(2-x) ) as a product of binomials, first simplify the expression. Notice that ( 2 - x ) can be rewritten as ( -(x - 2) ), so ( 3(2-x) = -3(x-2) ). Combining the terms, we have ( x(x-2) - 3(x-2) = (x-2)(x-3) ). Thus, the expression can be factored as ( (x-2)(x-3) ).

How do you make 37 out of 10 numbers?

To make 37 out of 10 numbers, you can use a combination of addition, subtraction, multiplication, and division with those numbers. For example, if you have the numbers 1 through 10, you might add certain numbers together (like 10 + 9 + 8 + 7 + 3) or use a formula that incorporates operations to achieve the total of 37. Alternatively, you could set up an equation involving these numbers to solve for a combination that equals 37.

What number is both odd and composite number?

The number 9 is an example of a number that is both odd and composite. An odd number is one that is not divisible by 2, and a composite number is one that has more than two positive divisors. In the case of 9, its divisors are 1, 3, and 9, making it composite as well as odd. Other examples include 15, 21, and 25.

What is 6007?

The number 6007 can refer to a variety of things depending on the context, such as a numerical value, a code, or a designation. In mathematics, it is simply an integer that follows 6006 and precedes 6008. If you're referring to a specific context, such as a postal code, area code, or model number, please provide more details for a precise answer.

What 2 numbers are multiplied to equal 612?

There are infinitely many possible answers. One such is 1 times 612 = 612

What are people aged 50 to 59 called?

People aged 50 to 59 are often referred to as "middle-aged." This demographic is typically in a life stage characterized by various transitions, including career shifts, family changes, and considerations related to health and retirement.

What number is between 50 and 100?

Any number that is greater than 50, and smaller than 100, such as 51, 52, 53, 99, 50.1, etc.

If you want the number that is exactly halfway in between, calculate (50 + 100) / 2.

How many 2 digit prime numbers have 4 as one of their digits?

There are four 2-digit prime numbers that have 4 as one of their digits: 41, 43, 47, and 49. However, 49 is not a prime number because it is divisible by 7. So, the correct answer is three 2-digit prime numbers with 4 as one of their digits.

Why is 2 not a prime number?

2 is not a prime number because a prime number is defined as a number greater than 1 that has only two factors: 1 and itself. Since 2 only has these two factors, it meets the definition of a prime number.

Why is 2 prime?

2 is prime because it is a natural number greater than 1 that is only divisible by 1 and itself.

How do you spell the number 37?

'37' is 'Thirty seven'. Two separate words.

91 is a prime number true or false?

FALSE!!!!

91 is divisible by '7' Hence it is NOT a prime number.

What is the prime factorization of 245 using exponents?

The prime factorization of 245 is 5 x 7 x 7, or 5 x 7^2. This can be written in exponential form as 5 x 7^2, where 5 is raised to the power of 1 and 7 is raised to the power of 2. This means that 245 can be expressed as the product of its prime factors, with 5 occurring once and 7 occurring twice.

What are the numbers under B in bingo?

Oh, dude, the numbers under B in bingo can range from 1 to 15. So, technically, you can have any number from 1 to 15 under that B column. It's like the wild west of numbers, man. Just waiting to be called out and potentially make someone a bingo champion.

How do you find prime numbers between 65 and 75?

To find prime numbers between 65 and 75, you would first list out the numbers in that range: 66, 67, 68, 69, 70, 71, 72, 73, 74, 75. Next, you would test each number to see if it is divisible by any number other than 1 and itself. Prime numbers have only two factors: 1 and the number itself. By applying this divisibility test to each number in the range, you would identify the prime numbers between 65 and 75, which in this case are 67 and 71.

How many prime numbers are between 60 and 70?

There is only one prime number between 60 and 70, which is 61. A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. In this case, 61 fits the criteria as it is only divisible by 1 and itself.

What is the sum of the prime numbers less than 30?

2 + 3 + 5 + 7 + 11 + 13 + 17 + 19 + 23 + 29 = 129

the answer would be 49 because if you add 7 to, 42 that equals 49

42+7=49
