Ex 3.3, 3 Using divisibility tests, determine which of following numbers are divisible by 6: (f) 438750To check divisibility by 6 we check that Number is divisible by 2 Number is divisible by 3 Divisibility by 2 Since 438750 ends with 0 It is divisible by 2 Divisibility by 3 Sum of the digits = 4 + 3 + 8 + 7 + 5 + 0 = 27 Since 27 is divisible by 3 438750 is divisible by 3 Since 438750 is divisible by both 2 and 3 It is divisible by 6
