How do I find the factors or divisors of the number 787,351,042?

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 787,351,042, 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.

1 787,351,042

Next, we take the number 787,351,042 and divide it by 2.

In this case, 787,351,042 ÷ 2 = 393,675,521

If the quotient is a whole number, then 2 and 393,675,521 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 393,675,521 787,351,042

Now, we try dividing 787,351,042 by 3.

787,351,042 ÷ 3 = 262,450,347.3333

If the quotient is a whole number, then 3 and 262,450,347.3333 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 2 393,675,521 787,351,042

Let's try dividing by 4.

787,351,042 ÷ 4 = 196,837,760.5

If the quotient is a whole number, then 4 and 196,837,760.5 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 2 393,675,521 787,351,042

We keep dividing by the next largest number, in this case the number 5. If the quotient of 787,351,042 ÷ 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:

12234617,116,32734,232,654393,675,521787,351,042

All of the numbers in the table above can be evenly divided into the number 787,351,042.
