Ex 3.3, 2 Using divisibility tests, determine which of the following numbers are divisible by 4; by 8: (a) 572 Divisibility by 4 If last 2 digits are divisible by 4 Then, number is divisible by 4 Divisibility by 8 If last 3 digits are divisible by 8 Then, number is divisible by 8 Divisibility by 8 If last 3 digits are divisible by 8 Then, number is divisible by 8 Divisibility by 4 Last 2 digits are 72 Since remainder is 0, 72 is divisible by 4 ∴ 572 is divisible by 4 Divisibility by 8 Last 3 digits are 572 Since remainder is not 0 ∴ 572 is not divisible by 8
