No. 2 x 12 does not equal 42.
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.
2 x 3 x 7 = 42
The prime factorization of 42 is 2 x 3 x 7.2 x 3 x 7 = 422 x 3 x 7 = 42
21 isn't prime. The prime factorization of 42 is 2 x 3 x 7.
2 x 2 x 2 x 2 = 16 2 x 3 x 7 = 42
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.
42 = 2 x 3 x 7
16 = 2 x 2 x 2 x 2 42 = 2 x 3 x 7
2 x 3 x 5 = 30 2 x 3 x 7 = 42
The prime factorization for the number 12 is: 2 x 2 x 3
2 x 3 x 7 = 42 2 x 2 x 2 x 7 = 56
2 x 2 x 2 x 5 = 40 2 x 3 x 7 = 42
