If it divides evenly into the original number with no remainder, it's a factor.
Because 3 divides evenly into 27 with no remainder.
A regular polygon will tessellate if its interior angle divides 360 evenly.
add up all of the numbers together and if the sum is divisible by 3 then so is the original number.example:333+3=99/3=333/3=11JANE BROWN
When the first number can divide the second without remainder. The formal definition would be as follows: For integers x and y, x is a factor of y if there exists an integer n such that y = n*x
Divide the smaller number into the larger number. If it comes out evenly with no remainder, the larger number is a multiple of the smaller number. All even numbers are multiples of two.
you know that nineteen is a prime number because it only divides by one and itself. hopefully that helped

You know that it is a multiple of 9 if it divides into 9 equally.
If its not divisible by 2 evenly then it is an odd number.
1,3,5,9,15,27,45 I know this stuff and that's it.
Numbers are divisible by 8 if the number formed by the last three individual digits is evenly divisible by 8. For example, the last three digits of the number 3624 is 624, which is evenly divisible by 8 so 3624 is evenly divisible by 8.
