How do I find the factor combinations of the number 702,287?

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 702,287, 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.

1 702,287
-1 -702,287

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 702,287.

Example:
1 x 702,287 = 702,287
and
-1 x -702,287 = 702,287
Notice both answers equal 702,287

With that explanation out of the way, let's continue. Next, we take the number 702,287 and divide it by 2:

702,287 ÷ 2 = 351,143.5

If the quotient is a whole number, then 2 and 351,143.5 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:

1 702,287
-1 -702,287

Now, we try dividing 702,287 by 3:

702,287 ÷ 3 = 234,095.6667

If the quotient is a whole number, then 3 and 234,095.6667 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:

1 702,287
-1 -702,287

Let's try dividing by 4:

702,287 ÷ 4 = 175,571.75

If the quotient is a whole number, then 4 and 175,571.75 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:

1 702,287
-1 702,287
Keep dividing by the next highest number until you cannot divide anymore.

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

1171093791,8536,44341,311702,287
-1-17-109-379-1,853-6,443-41,311-702,287
