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.

Can you explain why the prime factorization of 42 is 21 2?
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.
Is 21 x 2 a prime factorization of 42?
No, 21 is not a prime number.
Is 21x 2 the only prime factorization of 42?
21 isn't prime. The prime factorization of 42 is 2 x 3 x 7.
Is prim factorization of 42 is 21 times 2?
No, prime factorization of 42 is not 21 x 2 because 21 is not a prime number and it can be further broken into primes as 3 x 7. So prime factorization of 42 is 2 x 3 x 7.
Is the prime factorization of 42 is 21 x 2?
No. Prime factorization is the method of expressing a number as the product of prime numbers. So, Prime factorization of 42 = 2x3x7
Why is is the prime factorization 42 21 2?
It's incomplete. 21 isn't prime. 42 21,2 7,3,2 2 x 3 x 7 = 42
Is prime factorization for 42 21 x 2?
No, 21 is not prime. Try 2 x 3 x 7.
Is prime factorization of 42 is 21 times 2?
No because 21 = 3 * 7 it is: 42 = 2 * 3 * 7
What is the prime factorization of 42 how do you get the answers?
42/2 = 21 21/3 = 7 7/7 = 1 So: 2*3*7 = 42
Is the prime factorization for 42 21x2?
you are almost there, you must split it one more time. 21 is divisible by 7 and 3, so the prime factorization of 42 is 7x3x2
What are the primes numbers of 42?
The prime factorization of 42 ia: 2 x 21 2 x 3 x 7. The prime prime factors of 42 are 2, 3, 7.
Is Audrey right that the prime factorization of 42 is 21 times 2. Is she right?
No. The prime factorisation of 42 = 3 x 7 x 2.
