Divisibility Rule of 5: Numbers that are divisible by 5 must end in 5 or 0. Illustration: Check whether 34,780 is divisible by 5 or not? Solution: For this rule, we just look at the last digit: 34,780. The last digit is a 0, so this number is divisible by 5. Illustration: Check whether 13,569 is divisible by 5 or not? Solution: Again, we will focus our attention on the last digit: 13,569. The last digit is  9, so this number is not divisible by 5.

Illustration: Check which of the following numbers are divisible by 5?

                  1236, 2525, 10000, 7898

Solution: As 1236, 7898 ends with digits 6, 8 respectively, hence these numbers are not divisible by 5. But 2525, 100000 ends with digits 5, 0 respectively. Hence these two numbers are divisible by 5.

Illustration: Check which of the following numbers are divisible by 5?

                  1235, - 5656, - 5250, 1002
