16 = 2 x 2 x 2 x 2
42 = 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
Method of prime factorization: Expressing each number as the product of prime numbers.P.F. of 16 = 2x2x2x2P.F. of 42 = 2x3x7G.C.F.(16, 42) = 2
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 isn't prime. The prime factorization of 42 is 2 x 3 x 7.
It is: 2*3*7 = 42
No, 16 is not prime. 2 x 2 x 2 x 2 is the prime factorization of 16.
42
No.
the LCM of 42 and 126 using a prime factorization is 2 times 2 times 3
42 = 2 × 3 × 7
