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.

How do you express 105 x 294 as a product of prime factors?
To express 105 x 294 as a product of prime factors, first factorize both numbers individually.
105 = 3 x 5 x 7 294 = 2 x 3 x 7 x 7
Then multiply the prime factors together to get the prime factorization of the product:
105 x 294 = (3 x 5 x 7) x (2 x 3 x 7 x 7) = 2 x 3^2 x 5 x 7^2
What is the number between 1 and 25?
The number between 1 and 25 is 13. In a set of consecutive integers, the number that falls exactly in the middle is found by taking the average of the two outermost numbers. In this case, (1 + 25) / 2 = 13.
Which 2 prime numbers times to make 91?
Oh, dude, you're hitting me with some math here! So, like, the two prime numbers that multiply to make 91 are 7 and 13. Yeah, it's like a little math puzzle, but hey, I got your back on this one!
What 2 prime numbers add together to make 91?
Well, isn't that a happy little math question! The two prime numbers that add up to 91 are 89 and 2. Remember, prime numbers are like little gems in the mathematical world, shining brightly with their unique properties. Keep exploring and discovering the beauty of numbers, my friend!
Is 9 a prime number and a factor of 18?
No, 9 is not a prime number because it has factors other than 1 and itself. In this case, 9 is a factor of 18 because 9 multiplied by 2 equals 18. Prime numbers are numbers that have exactly two factors, 1 and the number itself, while factors are numbers that can be multiplied together to get the original number.
What is the product of the first prime number and the fifth prime number?
Well, darling, the first prime number is 2 and the fifth prime number is 11. Multiply those bad boys together and you get 22. So, the product of the first prime number and the fifth prime number is 22. Math doesn't have to be boring, honey!
What is the number that ends with t and has 5 letters?
The number that ends with "t" and has 5 letters is "forty." This is because it is spelled with five letters and ends with the letter "t." It is important to note that this answer is based on the English language and may vary in other languages.
Write 130 as the product of prime numbers?
You have to break it down to get to prime numbers, so here it is:
130
10 13
5 2
2 x 5 x 13
How do you write 240 as the product of prime numbers?
To write 240 as the product of prime numbers, you need to find its prime factorization. Start by dividing 240 by the smallest prime number, 2, to get 120. Then divide 120 by 2 to get 60, and continue this process until you cannot divide any further. The prime factorization of 240 is 2 x 2 x 2 x 2 x 3 x 5, or 2^4 x 3 x 5.
42 is 75 percent of what number?
To find the number that 42 is 75% of, you can set up a proportion. Let x represent the unknown number. The proportion would be: 42 = 0.75x. To solve for x, divide both sides by 0.75, giving you x = 42 / 0.75 = 56. Therefore, 42 is 75% of 56.
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. In this case, using the digits 4, 1, and 0, the only possible combination is 41, which is a prime number because it is only divisible by 1 and 41 itself. Therefore, 41 is the prime number that can be formed using the digits 4, 1, and 0.
What are the prime numbers that are greater than 40 but less than 64?
The prime numbers between 40 and 64 are:
41 43 47 53 59 61
Oh, dude, prime numbers are like those cool loner numbers that only hang out with themselves and 1, right? So, if 486 wants to join the prime number club, it needs to be like, "Sorry, I'm not divisible by anything except myself and 1." But 486 is like, "Nah, I can be divided by 2, 3, 6, 9, 27, 54, 81, and 162." So yeah, 486 is not a prime number.
Oh, dude, we've got a real diva number here, causing a scene with all these remainders. So, when you divide it by 4, it's like "I've got 1 left," by 5 it's like "I've got 2 left," and by 6 it's like "I've got 3 left." The smallest number that fits this drama queen criteria is 59. It's like the perfect balance of being divided by 4, 5, and 6 and still having some leftovers to show off.
What number between 10 and 20 is divisible by both 4 and 6?
numbers between 10 and 20 is divisible by both 4 and 6 = 12 & 18
What are all the prime numbers between 0 and 10?
Oh, what a happy little question! Let's see... between 0 and 10, we have the prime numbers 2, 3, 5, and 7. They're like little gems shining brightly in the mathematical landscape, each one unique and special in its own way. Just like when you're painting, it's important to appreciate the beauty and simplicity of these numbers as they stand out among the others.
What is the difference between prime numbers and prime factor?
Prime numbers are integers greater than 1 that have no positive divisors other than 1 and themselves. Prime factors, on the other hand, are prime numbers that divide a given integer without leaving a remainder. In other words, prime factors are the prime numbers that, when multiplied together, result in the original integer. For example, the number 12 has prime factors of 2 and 3, as 2 * 2 * 3 = 12.
How many 2 digit prime numbers are there?
There are 21 two-digit prime numbers. The first two-digit prime number is 11, and the last two-digit prime number is 97. Prime numbers are numbers greater than 1 that are only divisible by 1 and themselves.
What is the sum of all prime numbers between 10 and 20?
Oh, what a delightful question! Let's take a moment to appreciate the beauty of prime numbers. The prime numbers between 10 and 20 are 11, 13, 17, and 19. When we add them together with a gentle brushstroke of mathematics, we get a sum of 60. Happy little primes indeed!
