How do I find the factors or divisors of the number 254,142,420?

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 254,142,420, 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.

1 254,142,420

Next, we take the number 254,142,420 and divide it by 2.

In this case, 254,142,420 ÷ 2 = 127,071,210

If the quotient is a whole number, then 2 and 127,071,210 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 127,071,210 254,142,420

Now, we try dividing 254,142,420 by 3.

254,142,420 ÷ 3 = 84,714,140

If the quotient is a whole number, then 3 and 84,714,140 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 84,714,140 127,071,210 254,142,420

Let's try dividing by 4.

254,142,420 ÷ 4 = 63,535,605

If the quotient is a whole number, then 4 and 63,535,605 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 63,535,605 84,714,140 127,071,210 254,142,420

We keep dividing by the next largest number, in this case the number 5. If the quotient of 254,142,420 ÷ 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:
