Question

Find the sum of all the numbers that are factors of 30 but are not factors of 18

Answer 1

Answer:

60

Step-by-step explanation:

Factors of 30 = 1, 2, 3, 5, 6, 10, 15, 30

Factors of 18 = 1, 2, 3, 6, 9, 18

Common Factors = 1, 2, 3, 6

Factors of 30 that aren't factors of 18 = 5, 10, 15, 30

Sum = 5 + 10 + 15 + 30

        = 60
