How do I find the factors or divisors of the number 155,172,360?

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 155,172,360, 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.

1 155,172,360

Next, we take the number 155,172,360 and divide it by 2.

In this case, 155,172,360 ÷ 2 = 77,586,180

If the quotient is a whole number, then 2 and 77,586,180 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 77,586,180 155,172,360

Now, we try dividing 155,172,360 by 3.

155,172,360 ÷ 3 = 51,724,120

If the quotient is a whole number, then 3 and 51,724,120 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 51,724,120 77,586,180 155,172,360

Let's try dividing by 4.

155,172,360 ÷ 4 = 38,793,090

If the quotient is a whole number, then 4 and 38,793,090 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 38,793,090 51,724,120 77,586,180 155,172,360

We keep dividing by the next largest number, in this case the number 5. If the quotient of 155,172,360 ÷ 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:
