How do I find the factors or divisors of the number 16,638?

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 16,638, 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 16,638

Next, we take the number 16,638 and divide it by 2.

In this case, 16,638 ÷ 2 = 8,319

If the quotient is a whole number, then 2 and 8,319 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 2 8,319 16,638

Now, we try dividing 16,638 by 3.

16,638 ÷ 3 = 5,546

If the quotient is a whole number, then 3 and 5,546 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 5,546 8,319 16,638

Let's try dividing by 4.

16,638 ÷ 4 = 4,159.5

If the quotient is a whole number, then 4 and 4,159.5 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 3 5,546 8,319 16,638

We keep dividing by the next largest number, in this case the number 5. If the quotient of 16,638 ÷ 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:

12364759941181411772823542,7735,5468,31916,638

All of the numbers in the table above can be evenly divided into the number 16,638.

Finally, for your reference, here are all of the divisor combinations of the number 16,638:

1 x 166382 x 83193 x 55466 x 277347 x 35459 x 28294 x 177118 x 141
