How do I find the factors or divisors of the number 428,455,320?

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 428,455,320, 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.

1 428,455,320

Next, we take the number 428,455,320 and divide it by 2.

In this case, 428,455,320 ÷ 2 = 214,227,660

If the quotient is a whole number, then 2 and 214,227,660 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 214,227,660 428,455,320

Now, we try dividing 428,455,320 by 3.

428,455,320 ÷ 3 = 142,818,440

If the quotient is a whole number, then 3 and 142,818,440 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 3 142,818,440 214,227,660 428,455,320

Let's try dividing by 4.

428,455,320 ÷ 4 = 107,113,830

If the quotient is a whole number, then 4 and 107,113,830 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 4 107,113,830 142,818,440 214,227,660 428,455,320

We keep dividing by the next largest number, in this case the number 5. If the quotient of 428,455,320 ÷ 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:
