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 1,317,173, 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 | 1,317,173 | |
| -1 | -1,317,173 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,317,173.
Example:
1 x 1,317,173 = 1,317,173
and
-1 x -1,317,173 = 1,317,173
Notice both answers equal 1,317,173
With that explanation out of the way, let's continue. Next, we take the number 1,317,173 and divide it by 2:
1,317,173 ÷ 2 = 658,586.5
If the quotient is a whole number, then 2 and 658,586.5 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 | 1,317,173 | |
| -1 | -1,317,173 |
Now, we try dividing 1,317,173 by 3:
1,317,173 ÷ 3 = 439,057.6667
If the quotient is a whole number, then 3 and 439,057.6667 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 | 1,317,173 | |
| -1 | -1,317,173 |
Let's try dividing by 4:
1,317,173 ÷ 4 = 329,293.25
If the quotient is a whole number, then 4 and 329,293.25 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 | 1,317,173 | |
| -1 | 1,317,173 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 61 | 143 | 151 | 671 | 793 | 1,661 | 1,963 | 8,723 | 9,211 | 21,593 | 101,321 | 119,743 | 1,317,173 |
| -1 | -11 | -13 | -61 | -143 | -151 | -671 | -793 | -1,661 | -1,963 | -8,723 | -9,211 | -21,593 | -101,321 | -119,743 | -1,317,173 |
