Ex 3.3, 2 Using divisibility tests, determine which of the following numbers are divisible by 4; by 8: (g) 21084 Divisibility by 4 Last 2 digits = 84 Since 84 is divisible by 4 ∴ 21084 is divisible by 4 Divisibility by 8 Last 3 digits = 084 = 84 Since 84 is not divisible by 8 ∴ 21084 is not divisible by 8
