The prime factorization for 21 is: 3x73 x 7 = 21
3 x 7 = 21, since both factors are prime, that is the prime factorization of 21.
The prime factorization of 21 is 3 x 7.
Do you mean, "What is the prime factorization of 21?"
The prime factorization for 21 is 3x7.
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.
The prime factorization of 21 is: 3 x 7
No, 21 is not prime.
No, 21 is not a prime number.
No. Prime factorization is the method of expressing a number as the product of prime numbers. So, Prime factorization of 42 = 2x3x7
21 = 3 x 7
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.
