Q: What are the factors or divisors of the number 401,988?

How do I find the factors or divisors of the number 401,988?

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 401,988, 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

401,988

Next, we take the number 401,988 and divide it by 2.

In this case, 401,988 ÷ 2 = 200,994

If the quotient is a whole number, then 2 and 200,994 are factors. Write them in the table below. If the quotient is not a whole number, skip to the next test.

Now, we try dividing 401,988 by 3.

401,988 ÷ 3 = 133,996

If the quotient is a whole number, then 3 and 133,996 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:

Let's try dividing by 4.

401,988 ÷ 4 = 100,497

If the quotient is a whole number, then 4 and 100,497 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:

We keep dividing by the next largest number, in this case the number 5. If the quotient of 401,988 ÷ 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:

All of the numbers in the table above can be evenly divided into the number 401,988.

Finally, for your reference, here are all of the divisor combinations of the number 401,988:

1 x 4019882 x 2009943 x 1339964 x 1004976 x 6699812 x 33499139 x 2892241 x 1668278 x 1446417 x 964482 x 834556 x 723
