How do I find the factors or divisors of the number 676,143,742?

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 676,143,742, 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.

1 676,143,742

Next, we take the number 676,143,742 and divide it by 2.

In this case, 676,143,742 ÷ 2 = 338,071,871

If the quotient is a whole number, then 2 and 338,071,871 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 338,071,871 676,143,742

Now, we try dividing 676,143,742 by 3.

676,143,742 ÷ 3 = 225,381,247.3333

If the quotient is a whole number, then 3 and 225,381,247.3333 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 2 338,071,871 676,143,742

Let's try dividing by 4.

676,143,742 ÷ 4 = 169,035,935.5

If the quotient is a whole number, then 4 and 169,035,935.5 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 2 338,071,871 676,143,742

We keep dividing by the next largest number, in this case the number 5. If the quotient of 676,143,742 ÷ 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:

12234614,698,77729,397,554338,071,871676,143,742
