Is 31 Divisible By 7?
Here we will show you how to find out if 31 is divisible by 7.
If you have access to a calculator, the easiest way to figure out if 31 is divisible by 7 may be to simply enter 31/7 into the calculator. If the quotient is an integer, then 31 is divisible by 7.
However, you can also determine if 31 is divisible by 7 using an alternate method.
Simply multiply the last digit by 2 and then subtract the product from the remaining digits.
If that difference is divisible by 7, then 31 is divisible by 7.
The last digit in 31 is 1 and the remaining digits are 3. Thus, the math to determine if 31 is divisible by 7 using our alternate method is:
3 - (1 x 2) = 1
Since 1 is not divisible by 7, 31 is also not divisible by 7.
Therefore, the answer to "Is 31 Divisible By 7?" is no.
(31 / 7 = 4.429)
