How do you know if a number can be divided by 10 evenly?

The Rule for 10: Numbers that are divisible by 10 need to be even and divisible by 5, because the prime factors of 10 are 5 and 2. Basically, this means that for a number to be divisible by 10, the last digit must be a 0. Take a look at the last digit: 23,890.

.

Keeping this in consideration, how do you know if a number is evenly divisible?

Divide even numbers by 2. By definition, an even number is one that is divisible by 2.. So to check if any number, no matter how long, is divisible by 2, look at the last digit. If the last digit is even, the entire number is divisible by 2. Remember that 0 is an even number.

One may also ask, how do you know a number is divisible? If any number ends in a two digit number that you know is divisible by 4 (e.g. 24, 04, 08, etc.), then the whole number will be divisible by 4 regardless of what is before the last two digits. Alternatively, one can simply divide the number by 2, and then check the result to find if it is divisible by 2.

Keeping this in view, what happens to a number when you divide it by 10?
