No, 21 isn't prime. Try 2 x 3 x 7.
The prime factors of 42 are 2, 3 and 7.
2 x 2 = 42 x 5 = 10The GCF is 2.
21 isn't prime. The prime factorization of 42 is 2 x 3 x 7.
Prime factors of 42 are: 2, 3 and 7 Prime factors of 237 are: 3 and 79
A Factor tree looks like this:... 42... / . \..2 ...21....... / . \.......3 . 7So the prime factors of 42 are 2 x 3 x 7
The prime factors of 42 are 2, 3 and 7.
Yes and they are: 2, 3 and 7
The prime factors of 42 are 2, 3, and 7. These prime numbers multiplied create 42.2*3*7 = 422 x 3 x 7 = 42.
8 = 2 x 2 x 2 42 = 2 x 3 x 7
42 = 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 prime.
No, 21 is not a prime number.
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.
It's incomplete. 21 isn't prime. 42 21,2 7,3,2 2 x 3 x 7 = 42
2 x 2 = 42 x 5 = 10The GCF is 2.
21 isn't prime. The prime factorization of 42 is 2 x 3 x 7.
