What generalization can you make about all multiples of 4?
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.
