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 1,317,755, 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 | 1,317,755 | |
| -1 | -1,317,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,317,755.
Example:
1 x 1,317,755 = 1,317,755
and
-1 x -1,317,755 = 1,317,755
Notice both answers equal 1,317,755
With that explanation out of the way, let's continue. Next, we take the number 1,317,755 and divide it by 2:
1,317,755 ÷ 2 = 658,877.5
If the quotient is a whole number, then 2 and 658,877.5 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 | 1,317,755 | |
| -1 | -1,317,755 |
Now, we try dividing 1,317,755 by 3:
1,317,755 ÷ 3 = 439,251.6667
If the quotient is a whole number, then 3 and 439,251.6667 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 | 1,317,755 | |
| -1 | -1,317,755 |
Let's try dividing by 4:
1,317,755 ÷ 4 = 329,438.75
If the quotient is a whole number, then 4 and 329,438.75 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 | 1,317,755 | |
| -1 | 1,317,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 37 | 85 | 185 | 419 | 629 | 2,095 | 3,145 | 7,123 | 15,503 | 35,615 | 77,515 | 263,551 | 1,317,755 |
| -1 | -5 | -17 | -37 | -85 | -185 | -419 | -629 | -2,095 | -3,145 | -7,123 | -15,503 | -35,615 | -77,515 | -263,551 | -1,317,755 |
