How do I find the factor combinations of the number 1,370,281?

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 1,370,281, 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 1,370,281
-1 -1,370,281

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 1,370,281.

Example:
1 x 1,370,281 = 1,370,281
and
-1 x -1,370,281 = 1,370,281
Notice both answers equal 1,370,281

With that explanation out of the way, let's continue. Next, we take the number 1,370,281 and divide it by 2:

1,370,281 ÷ 2 = 685,140.5

If the quotient is a whole number, then 2 and 685,140.5 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 1,370,281
-1 -1,370,281

Now, we try dividing 1,370,281 by 3:

1,370,281 ÷ 3 = 456,760.3333

If the quotient is a whole number, then 3 and 456,760.3333 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 1,370,281
-1 -1,370,281

Let's try dividing by 4:

1,370,281 ÷ 4 = 342,570.25

If the quotient is a whole number, then 4 and 342,570.25 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 1,370,281
-1 1,370,281
Keep dividing by the next highest number until you cannot divide anymore.

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

111434732,89731,867124,5711,370,281
-1-11-43-473-2,897-31,867-124,571-1,370,281
