Is 40 Divisible By 7?
Here we will show you how to find out if 40 is divisible by 7.
If you have access to a calculator, the easiest way to figure out if 40 is divisible by 7 may be to simply enter 40/7 into the calculator. If the quotient is an integer, then 40 is divisible by 7.
However, you can also determine if 40 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 40 is divisible by 7.
The last digit in 40 is 0 and the remaining digits are 4. Thus, the math to determine if 40 is divisible by 7 using our alternate method is:
4 - (0 x 2) = 4
Since 4 is not divisible by 7, 40 is also not divisible by 7.
Therefore, the answer to "Is 40 Divisible By 7?" is no.
(40 / 7 = 5.714)
