2 x 23 = 46
46 of them.
1*31 It is a prime number
No. Prime factors are the numbers that make up other numbers, but they have to be prime. Prime factorisation is the process of finding the prime numbers that create a number. This is when you multiply the prime numbers together and the product is the original number. For example: 20 5x4 5x2x2 This process is called prime factorisation. In this case, the prime numbers are 2, 2, and 5.
29, 31, 37, 41, 43... making 5 in all
Let ask you this.....what factors make up the number 19 when you multiply? Is there any? Now figure out what your answer is.

A multiplication sentence where prime factors total a given composite number is known as a prime factorization.
the prime factors of 72 are 2 and 3 6,12, and 1 (also factors) sum up to 19
1, 3, 9 1, 2, 23, 46
-46
Add them up. The prime factors of 30 are 2, 3 and 5. You can handle the rest.
