Obviously all multiples of 4 are divisible by 4 with no remainder -- that's the definition of a multiple.

All multiples of 4 are even numbers.

There is a test to tell if a number (even a really big one) is divisible by 4:  If the last two digits (tens and ones) are divisible by 4, then the whole number is divisible by 4.  So, you know immediately that 1,746,312 is divisible by 4 because the last two digits are 12, which is divisible by 4.

Lastly, there is a pattern to the 4 table.  Looking at the ones digit, the table goes 4 - 8 - 2 - 6 - 0 - 4 etc etc.

that the numbers will be even and if you are trying to solve the roots of a quadratic equation the root number will have a 2 in front of its root if it isnt a perfect root
