Because their quotient is a whole number.
You can easIly figure this out by using the fact that all even numbers are Divisible by 2. Because 312 is even it to Is also divisible by 2. Because 312 can be divided by mOre than itself and one, which is what a prime number is, it is composiTe.

All multiples of 10 end in a zero To be divisible by 10, the last digit must by a 0 The last digit of 312 is a 2 which is NOT a 0, so 312 is NOT divisible by 10.

312 is divisible by 9 but the answer is not a whole number, it is... 34.666 recurring.
624 is divisible by 312.

All multiples of 10 end in a zero To be divisible by 10, the last digit must by a 0 The last digit of 312 is a 2 which is NOT a 0, so 312 is NOT divisible by 10.
Finding divisibility by 3 and 9 are very easy to do. Simply add up the digits in the number and see if they are divisible by the number you are looking for. 3+1+3=7 and 7 is not divisible by 3, is 313 is not either. ◄ 3+1+2=6 and 6 is divisible by 3, so 312 is also. 312/3=104
