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.

How divisibility rules can help you find common factors?
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.
What are reasons of using the disivility rules?
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.
What is the official definition for multiples and factors?
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
How divisibility rules can help you find the prime factorization?
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.
What are the divisibility rules for 16 to 20?
Just doing the division is simpler, in most cases.
What are the divisibility rules to find at least four factors of the number 312?
A number is a multiple of 312 if it's a multiple of 3, 8 and 13 at the same time

What is the divisibility rules for 17?
17 is a prime number meaning it is not divisible by anything. There are no factors of 17.
How can divisibility rules help you find the prime factorization of a number?
they can help you by finding the two factors of the number given
How can knowing the divisibility rules help to determine if a number is prime or composite?
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.
What are the divisibility rules of all prime numbers?
The divisibility rules for a prime number is if it is ONLY divisible by 1, and itself.
What are reasons of using the disivility rules?

How understanding factors help to write divisibility rules?
Factors of numbers are divisible by them with no remainders
What number goes into all of the divisibility rules?
The number 0.
What are divisibility rules used for in real life?
You use divisibility rules t determine whether a particular number is (or is not) a factor of another number. If it is a factor, you can reduce the numbers involved to smaller numbers.You might want to find factors to simplify fractions or to add or subtract factions.
What divisibility rules could be used to determine some factors of 375?
claah!
How do divisibility rules help you find factors of a number?
If you know that a number is divisible by three, then you know that three and the number that results from the dividing are both factors of the original number. If you know that a number is not divisible by three, then you won't waste time performing that function. It's rare that the first factor other than one isn't a number between two and ten. If you know the divisibility rules, it will make factoring easier and faster.
