Take the number 3336. You know it's divisible by 1 because everything is. You know it's divisible by 2 because it's even. You know it's divisible by 3 because the digits add up to a multiple of 3 and you know it's divisible by 4 because the last two digits are divisible by 4. So you've found at least four factors: 1,2,3 and 4. Wiki User

Just think of one. All numbers are divisible. But that's probably not what you wanted to know. It's more likely you want to know how to find what a number is divisible by. For that, it is necessary to familiarize yourself with the rules of divisibility.

If the number is even, it's divisible by 2.

If the sum of the digits is a multiple of 3, the whole number is divisible by 3.

If the last two digits are a multiple of 4, the whole number is divisible by 4.

If the last digit is a 0 or a 5, the whole number is divisible by 5.

If the number is even and divisible by 3, it's divisible by 6.

If the last digit doubled subtracted from the rest is a multiple of 7, the whole number is divisible by 7.

If the last three digits are a multiple of 8, the whole number is divisible by 8.

If the sum of the digits is a multiple of 9, the whole number is divisible by 9.

If the number ends in 0, it's divisible by 10.   Wiki User
