Negative numbers don't have prime factorizations.

2 x 3 x 7 = 42 3 x 3 x 7 = 63

Prime Factorization of 42No, 21 X 2 is not the prime factorization of 42 because 21 is a composite number.2 X 3 X 7 is the prime factorization of 42 because all the factors are prime numbers.To arrive at the prime factorization in this particular case, you had to factor 21 down to its prime factors, not forgetting that one of the prime factors of 42 was already 2.2 X 21 = 423 X 7 = 21, so the prime factorization of 42 is:2 X 3 X 7No, 21 is not prime. Try 2 x 3 x 7.

2 x 2 = 42 x 5 = 10The GCF is 2.

The factors of 42 are: 1 2 3 6 7 14 21 42

Negative numbers don't have prime factorizations.

Yes and they are: 2, 3 and 7

42 = 2 x 3 x 7.

8 = 2 x 2 x 2 42 = 2 x 3 x 7

2 x 3 x 7 = 42 3 x 3 x 7 = 63

No, 21 is not prime.

In actual fact, the prime factorization of 42 is not 21 x 2, as 21 is not a prime number. The complete prime factorization of 42 is 2 x 3 x 7.

No, 21 is not a prime number.

It's incomplete. 21 isn't prime. 42 21,2 7,3,2 2 x 3 x 7 = 42

Prime factorization is finding the factors of a number that are all prime. Here's how you do it: Find 2 factors of your number. Then look at your 2 factors and determine if one or both of them is not prime. If it is not a prime factor it. Repeat this process until all your factors are prime. Here's an example:Find the prime factors of the number 84: 84 / \ 42 x 2 (84 is 42 times 2) / \ 21 x 2 (42 is 21 times 2) / \ 7 x 3 (21 is 7 times 3) (7 and 3 are both prime, so we stop!)So the prime factors of 84 are 7 x 3 x 2 x 2.

It's incomplete. 21 isn't prime. 42 21,2 7,3,2 2 x 3 x 7 = 42
