Q: What are the factors or divisors of the number 381,540?

How do I find the factors or divisors of the number 381,540?

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 381,540, 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

381,540

Next, we take the number 381,540 and divide it by 2.

In this case, 381,540 ÷ 2 = 190,770

If the quotient is a whole number, then 2 and 190,770 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 381,540 by 3.

381,540 ÷ 3 = 127,180

If the quotient is a whole number, then 3 and 127,180 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.

381,540 ÷ 4 = 95,385

If the quotient is a whole number, then 4 and 95,385 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 381,540 ÷ 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 381,540.

Finally, for your reference, here are all of the divisor combinations of the number 381,540:
