How can I tell if 3360 is divisible by 24 without doing division?

Math 
drwls,
See if 3360 contains prime factors that can be multiplied together to get 24.
But dividing by 24 directly is easier.
3360 = 336*5*2
= 112*3*5*2
= 8*7*2*3*5*2
There is a factor of 8*3 = 24 in that group

JeffGorden,
Go back to school or use a calculator?
