How do I find the factors or divisors of the number 210,987?

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 210,987, 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.

1 210,987

Next, we take the number 210,987 and divide it by 2.

In this case, 210,987 ÷ 2 = 105,493.5

If the quotient is a whole number, then 2 and 105,493.5 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

1 210,987

Now, we try dividing 210,987 by 3.

210,987 ÷ 3 = 70,329

If the quotient is a whole number, then 3 and 70,329 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 3 70,329 210,987

Let's try dividing by 4.

210,987 ÷ 4 = 52,746.75

If the quotient is a whole number, then 4 and 52,746.75 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 3 70,329 210,987

We keep dividing by the next largest number, in this case the number 5. If the quotient of 210,987 ÷ 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:

1379172151631191531973575911,0711,3791,7733,3494,13710,04712,41123,44330,14170,329210,987

All of the numbers in the table above can be evenly divided into the number 210,987.

Finally, for your reference, here are all of the divisor combinations of the number 210,987:
