How do I find the factors or divisors of the number 688,722,615?

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 688,722,615, 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.

1 688,722,615

Next, we take the number 688,722,615 and divide it by 2.

In this case, 688,722,615 ÷ 2 = 344,361,307.5

If the quotient is a whole number, then 2 and 344,361,307.5 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 688,722,615

Now, we try dividing 688,722,615 by 3.

688,722,615 ÷ 3 = 229,574,205

If the quotient is a whole number, then 3 and 229,574,205 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 3 229,574,205 688,722,615

Let's try dividing by 4.

688,722,615 ÷ 4 = 172,180,653.75

If the quotient is a whole number, then 4 and 172,180,653.75 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 3 229,574,205 688,722,615

We keep dividing by the next largest number, in this case the number 5. If the quotient of 688,722,615 ÷ 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:
