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 1,313,641, it is easier to work with a table - it's called factoring from the outside in.
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 | 1,313,641 | |
| -1 | -1,313,641 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,313,641.
Example:
1 x 1,313,641 = 1,313,641
and
-1 x -1,313,641 = 1,313,641
Notice both answers equal 1,313,641
With that explanation out of the way, let's continue. Next, we take the number 1,313,641 and divide it by 2:
1,313,641 ÷ 2 = 656,820.5
If the quotient is a whole number, then 2 and 656,820.5 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 | 1,313,641 | |
| -1 | -1,313,641 |
Now, we try dividing 1,313,641 by 3:
1,313,641 ÷ 3 = 437,880.3333
If the quotient is a whole number, then 3 and 437,880.3333 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 | 1,313,641 | |
| -1 | -1,313,641 |
Let's try dividing by 4:
1,313,641 ÷ 4 = 328,410.25
If the quotient is a whole number, then 4 and 328,410.25 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 | 1,313,641 | |
| -1 | 1,313,641 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 19 | 49 | 83 | 119 | 133 | 323 | 581 | 833 | 931 | 1,411 | 1,577 | 2,261 | 4,067 | 9,877 | 11,039 | 15,827 | 26,809 | 69,139 | 77,273 | 187,663 | 1,313,641 |
| -1 | -7 | -17 | -19 | -49 | -83 | -119 | -133 | -323 | -581 | -833 | -931 | -1,411 | -1,577 | -2,261 | -4,067 | -9,877 | -11,039 | -15,827 | -26,809 | -69,139 | -77,273 | -187,663 | -1,313,641 |
