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.
The prime factorization for 21 is 3x7.
Do you mean, "What is the prime factorization of 21?"
The prime number is the prime factorization. For example, the prime factorization of the prime number 3 is 3. Get it?
No, 21 is not a prime number. But Audrey knew that.
21 x 2 does not equal 40. 21 is not a prime number.
