How do I find the factors or divisors of the number 245,410,020?

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 245,410,020, 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.

1 245,410,020

Next, we take the number 245,410,020 and divide it by 2.

In this case, 245,410,020 ÷ 2 = 122,705,010

If the quotient is a whole number, then 2 and 122,705,010 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 122,705,010 245,410,020

Now, we try dividing 245,410,020 by 3.

245,410,020 ÷ 3 = 81,803,340

If the quotient is a whole number, then 3 and 81,803,340 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 81,803,340 122,705,010 245,410,020

Let's try dividing by 4.

245,410,020 ÷ 4 = 61,352,505

If the quotient is a whole number, then 4 and 61,352,505 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 61,352,505 81,803,340 122,705,010 245,410,020

We keep dividing by the next largest number, in this case the number 5. If the quotient of 245,410,020 ÷ 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.
