It is: 2*2*7 = 28
256 = 28
2 x 2 x 7 = 28
As a product of its prime factors: 2*2*7 = 28
The factors of 168 are: 1 2 3 4 6 7 8 12 14 21 24 28 42 56 84 168 The prime factors are: 2 x 2 x 2 x 3 x 7
As a product of its prime factors: 2*23 = 46 As a product of its prime factors: 2*2*7 = 28
It is: 2*2*7 = 28
7
2 x 2 x 7 = 28
256 = 28

The factors of 168 are: 1 2 3 4 6 7 8 12 14 21 24 28 42 56 84 168 The prime factors are: 2 x 2 x 2 x 3 x 7
We are sometimes asked to rewrite a composite number as a product of its prime factorization. That's redundant, since a prime factorization is a product by definition. The (product of the) prime factorization of 36 is 2 x 2 x 3 x 3.
28 = 2 × 2 × 7 = 2² × 7.
The prime factors of 28 are 2 and 7. The prime factors of 42 are 2, 3, and 7.
To find the HCF of two numbers, you need to express them in their prime factors: 8 = 2x2x2 28 = 2x2x7 The next step is to identify any common prime factors. In this case both numbers have two 2s as prime factors. Multiply these together and you get: 2x2 = 4 Thus 4 is the hcf of 8 and 28.
