First, you have to find the number that is a multiple of 7. That number is 126 because 7 x 18 = 126. Then, you need to find the prime factorization. You can do that by starting with any factor pair of 126 and keep factoring the composite factors until all factors are prime.

126:

2 x 61

Since 2 and 61 are prime, that is the prime factorization of 126.

You can't have prime factorization without having a number to factor.


What is a Prime Factorization and What is an example?

A prime factorization is the unique way to list any integer greater than 1 as a product of prime numbers. An example of the prime factorization of a composite number is 20=2*2*5 or 20=2^2*5. The prime factorization of a prime number is itself. e.g. 11=11.

Prime factorization 0f 58?

58=2*29; both 2 and 29 are prime, thus this is the prime factorization. In general, a prime factorization is a list of primes that comprise the number. For instance, 100: 100=2*50=2*2*25=2*2*5*5 => prime factorization is 2^2*5^2


What is the prime factorization of 2x2x7x7?

Prime factorization is a list of all the primes that multiply to make the original number. Thus to find that number you just multiply all these numbers together. In this case we have 2, 2, 7 and 7, so multiply them together to get: 2x2x7x7 = 296. Therefore, 2x2x7x7 is the prime factorization of 296.
