Is 20 Divisible By 7?
Here we will show you how to find out if 20 is divisible by 7.
If you have access to a calculator, the easiest way to figure out if 20 is divisible by 7 may be to simply enter 20/7 into the calculator. If the quotient is an integer, then 20 is divisible by 7.
However, you can also determine if 20 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 20 is divisible by 7.
The last digit in 20 is 0 and the remaining digits are 2. Thus, the math to determine if 20 is divisible by 7 using our alternate method is:
2 - (0 x 2) = 2
Since 2 is not divisible by 7, 20 is also not divisible by 7.
Therefore, the answer to "Is 20 Divisible By 7?" is no.
(20 / 7 = 2.857)
