No because its prime factorization is: 2*3*7 = 42

No. Prime factorization is the method of expressing a number as the product of prime numbers. So, Prime factorization of 42 = 2x3x7

No.

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.

21 isn't prime. The prime factorization of 42 is 2 x 3 x 7.

It is: 2*3*7 = 42

42 = 2*3*7

It is: 2*3*7 = 42

The prime factorization of 42 does not use exponents: 2 x 3 x 7

No.

42

-42 = -1*2*3*7

42 = 2 × 3 × 7

Negative numbers don't have prime factorizations.

The prime factorization of 14 = 2 x 7, and the prime factorization of 42 = 2 x 3 x 7

the LCM of 42 and 126 using a prime factorization is 2 times 2 times 3

2, 3 and 7

2, 3 and 7

The prime factorisation of 42 is 2*3*7.

They are: 37+5 = 42

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.

No, 21 is not a prime number.

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.

No, 21 isn't prime. 2 x 3 x 7 = 42
