How do I find the factors or divisors of the number 220,730,172?

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 220,730,172, 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.

1 220,730,172

Next, we take the number 220,730,172 and divide it by 2.

In this case, 220,730,172 ÷ 2 = 110,365,086

If the quotient is a whole number, then 2 and 110,365,086 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 110,365,086 220,730,172

Now, we try dividing 220,730,172 by 3.

220,730,172 ÷ 3 = 73,576,724

If the quotient is a whole number, then 3 and 73,576,724 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 3 73,576,724 110,365,086 220,730,172

Let's try dividing by 4.

220,730,172 ÷ 4 = 55,182,543

If the quotient is a whole number, then 4 and 55,182,543 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 3 4 55,182,543 73,576,724 110,365,086 220,730,172

We keep dividing by the next largest number, in this case the number 5. If the quotient of 220,730,172 ÷ 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:
