How do I find the factors or divisors of the number 343,121,040?

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 343,121,040, 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.

1 343,121,040

Next, we take the number 343,121,040 and divide it by 2.

In this case, 343,121,040 ÷ 2 = 171,560,520

If the quotient is a whole number, then 2 and 171,560,520 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 171,560,520 343,121,040

Now, we try dividing 343,121,040 by 3.

343,121,040 ÷ 3 = 114,373,680

If the quotient is a whole number, then 3 and 114,373,680 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 3 114,373,680 171,560,520 343,121,040

Let's try dividing by 4.

343,121,040 ÷ 4 = 85,780,260

If the quotient is a whole number, then 4 and 85,780,260 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 85,780,260 114,373,680 171,560,520 343,121,040

We keep dividing by the next largest number, in this case the number 5. If the quotient of 343,121,040 ÷ 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:
