How do I find the factors or divisors of the number 355,545,198?

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 355,545,198, 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.

1 355,545,198

Next, we take the number 355,545,198 and divide it by 2.

In this case, 355,545,198 ÷ 2 = 177,772,599

If the quotient is a whole number, then 2 and 177,772,599 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 177,772,599 355,545,198

Now, we try dividing 355,545,198 by 3.

355,545,198 ÷ 3 = 118,515,066

If the quotient is a whole number, then 3 and 118,515,066 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 3 118,515,066 177,772,599 355,545,198

Let's try dividing by 4.

355,545,198 ÷ 4 = 88,886,299.5

If the quotient is a whole number, then 4 and 88,886,299.5 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 3 118,515,066 177,772,599 355,545,198

We keep dividing by the next largest number, in this case the number 5. If the quotient of 355,545,198 ÷ 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:
