How do I find the factor combinations of the number 705,180?

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 divisors of larger numbers. To find the factor combinations of the number 705,180, it is easier to work with a table - it's called factoring from the outside in.

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. Then, below that, write the numbers as a negative as well.

1 705,180
-1 -705,180

Why are the negative numbers included?

When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 705,180.

Example:
1 x 705,180 = 705,180
and
-1 x -705,180 = 705,180
Notice both answers equal 705,180

With that explanation out of the way, let's continue. Next, we take the number 705,180 and divide it by 2:

705,180 ÷ 2 = 352,590

If the quotient is a whole number, then 2 and 352,590 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 352,590 705,180
-1 -2 -352,590 -705,180

Now, we try dividing 705,180 by 3:

705,180 ÷ 3 = 235,060

If the quotient is a whole number, then 3 and 235,060 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 235,060 352,590 705,180
-1 -2 -3 -235,060 -352,590 -705,180

Let's try dividing by 4:

705,180 ÷ 4 = 176,295

If the quotient is a whole number, then 4 and 176,295 are factors. In this case, the quotient is a whole number. Write them in the table inside the other two factors like the below example. Don't forget to write the negative numbers too!

Here is what our table should look like at this step:

1 2 3 4 176,295 235,060 352,590 705,180
-1 -2 -3 -4 -176,295 -235,060 -352,590 705,180
Keep dividing by the next highest number until you cannot divide anymore.

If you did it right, you will end up with this table:
