How do I find the factors or divisors of the number 420,242,644?

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 420,242,644, 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.

1 420,242,644

Next, we take the number 420,242,644 and divide it by 2.

In this case, 420,242,644 ÷ 2 = 210,121,322

If the quotient is a whole number, then 2 and 210,121,322 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 210,121,322 420,242,644

Now, we try dividing 420,242,644 by 3.

420,242,644 ÷ 3 = 140,080,881.3333

If the quotient is a whole number, then 3 and 140,080,881.3333 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 2 210,121,322 420,242,644

Let's try dividing by 4.

420,242,644 ÷ 4 = 105,060,661

If the quotient is a whole number, then 4 and 105,060,661 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 4 105,060,661 210,121,322 420,242,644

We keep dividing by the next largest number, in this case the number 5. If the quotient of 420,242,644 ÷ 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:

1246,16312,32617,04724,65234,09468,188105,060,661210,121,322420,242,644

All of the numbers in the table above can be evenly divided into the number 420,242,644.
