What are the prime factors of 700? A. 2 * 2 * 2 * 5 * 5 * 7 B. 350 * 2 C. 2 * 2 * 25 * 7 D. 2 * 2 * 5 * 5 * 7

D

Step-by-step explanation:

divide by the prime numbers 2, 3, 5, 7 until 1 is reached. The prime factorisation is the product of the prime numbers we have divided by.

Note if a particular value does not divide by a prime, move on to the next prime.

divide 700 by 2

700 : 2 = 350 ← divide by 2 again ⇒ 2

350 : 2 = 175 : now divide by 5 ⇒ 2

175 : 5 = 35 ← divide by 5 again ⇒ 5

35 : 5 = 7 ← now divide by 7 ⇒ 5

7 : 7 = 1 ← factored when 1 is reached ⇒ 7

700 = 2 * 2 * 5 * 5 * 7 → D
