How do I find the factors or divisors of the number 387,573,428?

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 387,573,428, 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.

1 387,573,428

Next, we take the number 387,573,428 and divide it by 2.

In this case, 387,573,428 ÷ 2 = 193,786,714

If the quotient is a whole number, then 2 and 193,786,714 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 193,786,714 387,573,428

Now, we try dividing 387,573,428 by 3.

387,573,428 ÷ 3 = 129,191,142.6667

If the quotient is a whole number, then 3 and 129,191,142.6667 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 2 193,786,714 387,573,428

Let's try dividing by 4.

387,573,428 ÷ 4 = 96,893,357

If the quotient is a whole number, then 4 and 96,893,357 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 96,893,357 193,786,714 387,573,428

We keep dividing by the next largest number, in this case the number 5. If the quotient of 387,573,428 ÷ 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:

1241122441,0932,1864,3728,05912,02316,11824,04632,23648,09288,649177,298354,5968,808,48717,616,97435,233,94896,893,357193,786,714387,573,428

All of the numbers in the table above can be evenly divided into the number 387,573,428.
