How to calculate factors of 40

The factors are numbers that can divide 40 without remainder.

Every number is divisible by itself and 1.

Calculating factors of 40

40/1 = 40        gives remainder 0 and so are divisible by 1
40/2 = 20        gives remainder 0 and so are divisible by 2
40/4 = 10        gives remainder 0 and so are divisible by 4
40/5 =       gives remainder 0 and so are divisible by 5
40/8 =       gives remainder 0 and so are divisible by 8
40/10 =       gives remainder 0 and so are divisible by 10
40/20 =       gives remainder 0 and so are divisible by 20
40/40 =       gives remainder 0 and so are divisible by 40

Other Integer Numbers, 3, 6, 7, 9, 11, 12, 13, 14, 15, 16, 17, 18, 19, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, divides with remainder, so cannot be factors of 40.

Only whole numbers and intergers can be converted to factors.



Factors of 40 that add up to numbers

Factors of 40 that add up to 90 =1 + 2 + 4 + 5 + 8 + 10 + 20 + 40

Factors of 40 that add up to 3 = 1 + 2

Factors of 40 that add up to 7 = 1 + 2 + 4

Factors of 40 that add up to 12 = 1 + 2 + 4 + 5

Factor of 40 in pairs

1 x 40, 2 x 20, 4 x 10, 5 x 8, 8 x 5, 10 x 4, 20 x 2, 40 x 1

1 and 40 are a factor pair of 40 since 1 x 40= 40

2 and 20 are a factor pair of 40 since 2 x 20= 40

4 and 10 are a factor pair of 40 since 4 x 10= 40

5 and 8 are a factor pair of 40 since 5 x 8= 40

8 and 5 are a factor pair of 40 since 8 x 5= 40

10 and 4 are a factor pair of 40 since 10 x 4= 40

20 and 2 are a factor pair of 40 since 20 x 2= 40

40 and 1 are a factor pair of 40 since 40 x 1= 40




We get factors of 40 numbers by finding numbers that can divide 40 without remainder or alternatively numbers that can multiply together to equal the target number being converted.

In considering numbers than can divide 40 without remainders. So we start with 1, then check 2,3,4,5,6,7,8,9, etc and 40

Getting factors is done by dividing 40 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.
