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.

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.

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.

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

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

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.

21 isn't prime, 2 x 3 x 7 = 42

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

No because 21 = 3 * 7 it is: 42 = 2 * 3 * 7

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

No, 21 is not prime. Try 2 x 3 x 7.

No. Prime factorizatio n of 42 = 2 x 3 x 7

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

42/2 = 21 21/3 = 7 7/7 = 1 So: 2*3*7 = 42

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

No. The prime factorisation of 42 = 3 x 7 x 2.

No, 21 is not a prime number. But Audrey knew that.

The prime factorization of 42 is 2x3x7. The prime factors are 2, 3, and 7. There are eight total factors of 42: 1, 2, 3, 6, 7, 14, 21, and 42.

21 and 6 are two composite numbers that have 42 as a common multiple. One of the prime factors of 42, which is 3, is a prime factor of 21 and 6 as well. The prime factorization of 42 (2 x 3 x 7) includes the prime factorization of 21 (3 x 7) and 6 (2 x 3).

It is: 2*3*7 = 42

42 = 2*3*7

It is: 2*3*7 = 42

*)1 7)7 3)21 2)42 The prime factorization of 42 is 2 x 3 x 7.

The prime factor decomposition of 84 is: 2 x 2 x 3 x 7 If you want to see my working (in case I made a mistake): 84/2=42 (42 is not prime), 42/2=21 (21 is not prime), 21/3=7 (7 is prime, so stop here) factors: 2,2,3 and 7
