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 1,311,703, 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 | 1,311,703 | |
| -1 | -1,311,703 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,311,703.
Example:
1 x 1,311,703 = 1,311,703
and
-1 x -1,311,703 = 1,311,703
Notice both answers equal 1,311,703
With that explanation out of the way, let's continue. Next, we take the number 1,311,703 and divide it by 2:
1,311,703 ÷ 2 = 655,851.5
If the quotient is a whole number, then 2 and 655,851.5 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 | 1,311,703 | |
| -1 | -1,311,703 |
Now, we try dividing 1,311,703 by 3:
1,311,703 ÷ 3 = 437,234.3333
If the quotient is a whole number, then 3 and 437,234.3333 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 | 1,311,703 | |
| -1 | -1,311,703 |
Let's try dividing by 4:
1,311,703 ÷ 4 = 327,925.75
If the quotient is a whole number, then 4 and 327,925.75 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 | 1,311,703 | |
| -1 | 1,311,703 |
If you did it right, you will end up with this table:
| 1 | 17 | 19 | 31 | 131 | 323 | 527 | 589 | 2,227 | 2,489 | 4,061 | 10,013 | 42,313 | 69,037 | 77,159 | 1,311,703 |
| -1 | -17 | -19 | -31 | -131 | -323 | -527 | -589 | -2,227 | -2,489 | -4,061 | -10,013 | -42,313 | -69,037 | -77,159 | -1,311,703 |
