WebJun 7, 2024 · When we divide N by 3, the quotient will be divisible by 7. Since the quotient decides how many groups we get, when we make groups of 3, we will get 7 groups or 14 groups or 21 groups etc. Hence we will be able to club each of the 7 groups to make groups of 21. Hence, N will be completely divisible by 21. Let’s consider another scenario now. WebA number is divisible by 21 if it is divisible by 3 and 7.
