Question

Write 28 as a product of its prime factors, write factors in order from smallest to largest

Answer 1

28=2x2x7
28=4x7 but 4 is not a prime number so you split it into its factors which are 2 and 2. The 2s are prime numbers and so is 7. Therefore, 28=2x2x7

Answer 2

2 × 2 × 7

Explanation:

start dividing by the lowest prime and work up until 1 is reached

28 ÷ 2 = 14

14 ÷ 2 = 7

7 ÷ 7 = 1

then

28 = 2 × 2 × 7 = 2² × 7
