We get factors of 640 numbers by finding numbers that can divide 640 without remainder or alternatively numbers that can multiply together to equal the target number being converted.

In considering numbers than can divide 640 without remainders. So we start with 1, then check 2,3,4,5,6,7,8,9, etc and 640

Getting factors is done by dividing 640 with numbers lower to it in value to find the one that will not leave remainder. Numbers that divide without remainders are the factors.

Factors are whole numbers or integers that are multiplied together to produce a given number. The integers or whole numbers multiplied are factors of the given number. If x multiplied by y = z then x and y are factors of z.

if for instance you want to find the factors of 20. You will have to find combination of numbers that when it is multiplied together will give 20. Example here is 5 and 4 because when you multiplied them, it will give you 20. so they are factors of the given number 20. Also 1 and 20, 2 and 10 are factors of 20 because 1 x 20 = 20 and 2 x 10 = 20. The factors of the given interger number 20 are 1, 2, 4, 5, 10, 20

To calculate factors using this tool, you will enter positive integers, because the calculator will only allow positive values, to calculate factors of a number. if you need to calculate negative numbers, you enter the positive value, get the factors and duplicate the answer yourself with all the give positive factors as negatives like as -5 and -6 as factors of number 30. On the other hand this calculator will give you both negative factors and positive integers for numbers. For instance, -2 , -3,-4 etc.

factors is like division in maths, because it gives all numbers that divide evenly into a number with no remainder. example is number 8. it is is evenly divisible by 2 and 4, which means that both 2 and 4 are factors of number 10.
