Question

What is the divisibility rule of 7?

Answer 1

Here are two rules which can be utilized to test divisibility by 7: Rule 1: Remove the last digit, double it, subtract it from the truncated original number and continue doing this until only one digit remains. If this is 0 or 7, then the original number is divisible by7.

Answer 2
