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.
No, 21 is not a prime number.
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. Prime factorization is the method of expressing a number as the product of prime numbers. So, Prime factorization of 42 = 2x3x7
The prime factorization for 21 is: 3x73 x 7 = 21
The prime factorization of 399 is 3 x 7 x 19. 21 wouldn't be included since it isn't 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.
Do you mean, "What is the prime factorization of 21?"
The prime factorization for 21 is 3x7.
21 x 2 does not equal 40. 21 is not a prime number.
No, 21 is not a prime number. But Audrey knew that.
The prime number is the prime factorization. For example, the prime factorization of the prime number 3 is 3. Get it?
