How do I find the factors or divisors of the number 55,721,164?

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 55,721,164, 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 55,721,164

Next, we take the number 55,721,164 and divide it by 2.

In this case, 55,721,164 ÷ 2 = 27,860,582

If the quotient is a whole number, then 2 and 27,860,582 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 27,860,582 55,721,164

Now, we try dividing 55,721,164 by 3.

55,721,164 ÷ 3 = 18,573,721.3333

If the quotient is a whole number, then 3 and 18,573,721.3333 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 27,860,582 55,721,164

Let's try dividing by 4.

55,721,164 ÷ 4 = 13,930,291

If the quotient is a whole number, then 4 and 13,930,291 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 13,930,291 27,860,582 55,721,164

We keep dividing by the next largest number, in this case the number 5. If the quotient of 55,721,164 ÷ 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:

1242,6175,2345,32310,46810,64621,29213,930,29127,860,58255,721,164

All of the numbers in the table above can be evenly divided into the number 55,721,164.
