How do I find the factors or divisors of the number 165,580,140?

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 165,580,140, 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.

1 165,580,140

Next, we take the number 165,580,140 and divide it by 2.

In this case, 165,580,140 ÷ 2 = 82,790,070

If the quotient is a whole number, then 2 and 82,790,070 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 82,790,070 165,580,140

Now, we try dividing 165,580,140 by 3.

165,580,140 ÷ 3 = 55,193,380

If the quotient is a whole number, then 3 and 55,193,380 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 55,193,380 82,790,070 165,580,140

Let's try dividing by 4.

165,580,140 ÷ 4 = 41,395,035

If the quotient is a whole number, then 4 and 41,395,035 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 41,395,035 55,193,380 82,790,070 165,580,140

We keep dividing by the next largest number, in this case the number 5. If the quotient of 165,580,140 ÷ 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:
