How do I find the factors or divisors of the number 687,242,328?

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 687,242,328, 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.

1 687,242,328

Next, we take the number 687,242,328 and divide it by 2.

In this case, 687,242,328 ÷ 2 = 343,621,164

If the quotient is a whole number, then 2 and 343,621,164 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 343,621,164 687,242,328

Now, we try dividing 687,242,328 by 3.

687,242,328 ÷ 3 = 229,080,776

If the quotient is a whole number, then 3 and 229,080,776 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 3 229,080,776 343,621,164 687,242,328

Let's try dividing by 4.

687,242,328 ÷ 4 = 171,810,582

If the quotient is a whole number, then 4 and 171,810,582 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 4 171,810,582 229,080,776 343,621,164 687,242,328

We keep dividing by the next largest number, in this case the number 5. If the quotient of 687,242,328 ÷ 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:

12346812244182123164246328492984698,4171,396,8342,095,2512,793,6684,190,5025,587,3368,381,00416,762,00828,635,09757,270,19485,905,291114,540,388171,810,582229,080,776343,621,164687,242,328
