Is 55 Divisible By 7?
Here we will show you how to find out if 55 is divisible by 7.
If you have access to a calculator, the easiest way to figure out if 55 is divisible by 7 may be to simply enter 55/7 into the calculator. If the quotient is an integer, then 55 is divisible by 7.
However, you can also determine if 55 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 55 is divisible by 7.
The last digit in 55 is 5 and the remaining digits are 5. Thus, the math to determine if 55 is divisible by 7 using our alternate method is:
5 - (5 x 2) = -5
Since 5 is not divisible by 7, 55 is also not divisible by 7.
Therefore, the answer to "Is 55 Divisible By 7?" is no.
(55 / 7 = 7.857)
