Q: What are the factors or divisors of the number 397,458?

How do I find the factors or divisors of the number 397,458?

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 397,458, 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

397,458

Next, we take the number 397,458 and divide it by 2.

In this case, 397,458 ÷ 2 = 198,729

If the quotient is a whole number, then 2 and 198,729 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 397,458 by 3.

397,458 ÷ 3 = 132,486

If the quotient is a whole number, then 3 and 132,486 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.

397,458 ÷ 4 = 99,364.5

If the quotient is a whole number, then 4 and 99,364.5 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:

We keep dividing by the next largest number, in this case the number 5. If the quotient of 397,458 ÷ 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 397,458.

Finally, for your reference, here are all of the divisor combinations of the number 397,458:

1 x 3974582 x 1987293 x 1324866 x 662439 x 4416218 x 2208171 x 5598142 x 2799213 x 1866311 x 1278426 x 933622 x 639
