Every integer is divisible by 1. So 1 is a factor.
The number ends in a 2 and so is even. Therefore, 2 is a factor.
The sum of the digits is 3+1+2 = 6 which is divisible by 3 so 3 is a factor.
2 and 3 are both factors so 2*3 = 6 is a factor.
So, four factors are 1, 2, 3 and 6.

What number goes into 312?
The factors of 312 are 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, and 312
Divisibility rule -divisible by 12?
If a number is divisible by 3, and also by 4, then it is divisible by 12 - so you might use the divisibility rules for those two numbers. Although it might be simpler just to perform the division.
Divisibility rules of 4?
A number is divisible by 4 if and only if its last two digits are divisible by 4. For example, 53112 is divisible by 4, because the last two digits (12) are divisible by 4.
What are the 20 divisibility test?
To test divisibility for 20, you need to use the tests for divisibility by 4 and 5.The test for divisibility by 4 is that the last 2 digits of the number, given as a 2-digit number, are divisible by 4.Example for 4:We are testing the number 11042.42/4 = 10.5 which is not a whole number. Therefore 11042 is not divisible by 4.The test for divisibility by 5 is that the last digit of the number is either 5 or 0.
What is 312 divided by 4?
78
What are the least four factors of 312 using divisibility rule?
1, 2, 3 and 4
What are the divisibility rules to the number 312?
A number is a multiple of 312 if it's a multiple of 3, 8 and 13 at the same time For example 1,248 is a multiple of 312 because 1 + 2 + 4 + 8 = 15, which means it's a multiple of 3, ends in 248, which means it's a multiple of 8, and 124 + 8 x 4 = 156, which means it's a multiple of 13 The rule works because 312 = 2^3 x 3 x 13
What does it means to use the divisibility rules to find factor pairs for eighty?
Factors are divisors. If you know the divisibility rules, you know that 80 is divisible by 1, 2, 4, 5 and 8. If you divide 80 by those numbers, you find the other half of the factor pairs.
What are the 4 factors of 312?

What are factors of 312 a composite?
The composite factors of 312 are 4, 6, 8, 12, 24, 26, 39, 52, 78, 104, 156, 312
Factors of 312?
The factors of 312 are 1, 2, 3, 4, 6, 8, 12, 13, 24, 26, 39, 52, 78, 104, 156, and 312
How do you know when you fount all the factor pairs of 26?
You only have to test the numbers 1 through 5. If you know the rules of divisibility, you know that 3, 4 and 5 aren't factors.
