How do I find the factors or divisors of the number 840,263,380?

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 840,263,380, 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.

1 840,263,380

Next, we take the number 840,263,380 and divide it by 2.

In this case, 840,263,380 ÷ 2 = 420,131,690

If the quotient is a whole number, then 2 and 420,131,690 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 420,131,690 840,263,380

Now, we try dividing 840,263,380 by 3.

840,263,380 ÷ 3 = 280,087,793.3333

If the quotient is a whole number, then 3 and 280,087,793.3333 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 2 420,131,690 840,263,380

Let's try dividing by 4.

840,263,380 ÷ 4 = 210,065,845

If the quotient is a whole number, then 4 and 210,065,845 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 4 210,065,845 420,131,690 840,263,380

We keep dividing by the next largest number, in this case the number 5. If the quotient of 840,263,380 ÷ 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:
