How do I find the factor combinations of the number 692,176?

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 692,176, 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.

1 692,176
-1 -692,176

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 692,176.

Example:
1 x 692,176 = 692,176
and
-1 x -692,176 = 692,176
Notice both answers equal 692,176

With that explanation out of the way, let's continue. Next, we take the number 692,176 and divide it by 2:

692,176 ÷ 2 = 346,088

If the quotient is a whole number, then 2 and 346,088 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 2 346,088 692,176
-1 -2 -346,088 -692,176

Now, we try dividing 692,176 by 3:

692,176 ÷ 3 = 230,725.3333

If the quotient is a whole number, then 3 and 230,725.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

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

1 2 346,088 692,176
-1 -2 -346,088 -692,176

Let's try dividing by 4:

692,176 ÷ 4 = 173,044

If the quotient is a whole number, then 4 and 173,044 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 4 173,044 346,088 692,176
-1 -2 -4 -173,044 -346,088 692,176
Keep dividing by the next highest number until you cannot divide anymore.

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

12481643,26186,522173,044346,088692,176
-1-2-4-8-16-43,261-86,522-173,044-346,088-692,176
