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.

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.

A number is considered divisible by another number when the quotient between the two is a whole number.

Divisibility rules help you find the factors of a number. Once you've found the factors for two or more numbers, you can find what they have in common. Take 231 and 321. If you know the divisibility rules, you know that they are both divisible by 3, so 3 is a common factor.

You can always check on the divisibility of a number by dividing it into another number. But if you know the divisibility rules, you can get that information easier and faster.

Factors: Are numbers that are multiplied to make a product. You always have to write the factors in order. If you need to find the factors of a number you can use divisibility rules. (they are used to know if a number is divisible by another numberDivisibility rules: by 2 : if the number ends in an even number, 2,4,6,8....by 3: if the addition of the number is a multiple of 3by 4 : if the last two numbers are divisible by 4( zero is an exception)by 5: if the number ends in 0 or 5by 6: if the number is divisible by 2 and 3by 9: if the addition of the number is a multiple of 9by 10: if the number ends in 0.Example: the factors of 1,2,4,8,16 16 is divisible by those numbers.1x16 2x8 4x4Multiple: Is the product of a number multiplied with any other factor or factors.Multiples are endless!!!Example the first 10 multiples of 6 are: 6,12,18,24,30,36,42,48,54, 60the first 10 multiples of 2 are:2,4,6,8,10,12,14,16,18,20

Suppose you were trying to find the prime factorization of 123. You know that half of the divisors will be less than the square root. Since the square root is between 11 and 12, you only need to test 2, 3, 5, 7 and 11 as prime factors. If you know the rules of divisibility, you already know that 2 and 5 aren't factors and 3 is. It saves time.

Just doing the division is simpler, in most cases.

The answer will depend on the divisibility rules list.

Knowing the divisibility rules will help you by being able to recognize if a number has factors (other than one and itself) which are covered by the rules. This will save actually having to start doing divisions.
