How do I find the factors or divisors of the number 40,400,740?

Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the factors of larger numbers. To find the factors of the number 40,400,740, it is easiest to start from the outside in. Here's what we mean:

Outside in Factoring

We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table.

1 40,400,740

Next, we take the number 40,400,740 and divide it by 2.

In this case, 40,400,740 ÷ 2 = 20,200,370

If the quotient is a whole number, then 2 and 20,200,370 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 20,200,370 40,400,740

Now, we try dividing 40,400,740 by 3.

40,400,740 ÷ 3 = 13,466,913.3333

If the quotient is a whole number, then 3 and 13,466,913.3333 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

1 2 20,200,370 40,400,740

Let's try dividing by 4.

40,400,740 ÷ 4 = 10,100,185

If the quotient is a whole number, then 4 and 10,100,185 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Here is what our table should look like at this step:

1 2 4 10,100,185 20,200,370 40,400,740

We keep dividing by the next largest number, in this case the number 5. If the quotient of 40,400,740 ÷ 5 is a whole number, then 5 and your quotient are factors of the number.


Keep dividing by the next highest number until you cannot divide anymore.


What you will end up with is this table:

124510202,020,0374,040,0748,080,14810,100,18520,200,37040,400,740

All of the numbers in the table above can be evenly divided into the number 40,400,740.

Finally, for your reference, here are all of the divisor combinations of the number 40,400,740:

1 x 40400740
2 x 20200370
