How do I find the factors or divisors of the number 72,201,628?

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 72,201,628, 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 72,201,628

Next, we take the number 72,201,628 and divide it by 2.

In this case, 72,201,628 ÷ 2 = 36,100,814

If the quotient is a whole number, then 2 and 36,100,814 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 36,100,814 72,201,628

Now, we try dividing 72,201,628 by 3.

72,201,628 ÷ 3 = 24,067,209.3333

If the quotient is a whole number, then 3 and 24,067,209.3333 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 36,100,814 72,201,628

Let's try dividing by 4.

72,201,628 ÷ 4 = 18,050,407

If the quotient is a whole number, then 4 and 18,050,407 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 18,050,407 36,100,814 72,201,628

We keep dividing by the next largest number, in this case the number 5. If the quotient of 72,201,628 ÷ 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:

1243837661,53247,12994,258188,51618,050,40736,100,81472,201,628

All of the numbers in the table above can be evenly divided into the number 72,201,628.
