How do I find the factors or divisors of the number 13,421,642?

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 13,421,642, 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 13,421,642

Next, we take the number 13,421,642 and divide it by 2.

In this case, 13,421,642 ÷ 2 = 6,710,821

If the quotient is a whole number, then 2 and 6,710,821 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 6,710,821 13,421,642

Now, we try dividing 13,421,642 by 3.

13,421,642 ÷ 3 = 4,473,880.6667

If the quotient is a whole number, then 3 and 4,473,880.6667 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 6,710,821 13,421,642

Let's try dividing by 4.

13,421,642 ÷ 4 = 3,355,410.5

If the quotient is a whole number, then 4 and 3,355,410.5 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 6,710,821 13,421,642

We keep dividing by the next largest number, in this case the number 5. If the quotient of 13,421,642 ÷ 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:

12132616933839,70979,418516,2171,032,4346,710,82113,421,642

All of the numbers in the table above can be evenly divided into the number 13,421,642.
