### Is 21 x 2 the prime factorization of 42?

Prime Factorization of 42
No, 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 = 42
3 X 7 = 21, so the prime factorization of 42 is:
2 X 3 X 7
No, 21 is not prime. Try 2 x 3 x 7.
