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 1,691,767, 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 | 1,691,767 | |
| -1 | -1,691,767 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,691,767.
Example:
1 x 1,691,767 = 1,691,767
and
-1 x -1,691,767 = 1,691,767
Notice both answers equal 1,691,767
With that explanation out of the way, let's continue. Next, we take the number 1,691,767 and divide it by 2:
1,691,767 ÷ 2 = 845,883.5
If the quotient is a whole number, then 2 and 845,883.5 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 | 1,691,767 | |
| -1 | -1,691,767 |
Now, we try dividing 1,691,767 by 3:
1,691,767 ÷ 3 = 563,922.3333
If the quotient is a whole number, then 3 and 563,922.3333 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 | 1,691,767 | |
| -1 | -1,691,767 |
Let's try dividing by 4:
1,691,767 ÷ 4 = 422,941.75
If the quotient is a whole number, then 4 and 422,941.75 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 | 1,691,767 | |
| -1 | 1,691,767 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 127 | 173 | 889 | 1,211 | 1,397 | 1,903 | 9,779 | 13,321 | 21,971 | 153,797 | 241,681 | 1,691,767 |
| -1 | -7 | -11 | -77 | -127 | -173 | -889 | -1,211 | -1,397 | -1,903 | -9,779 | -13,321 | -21,971 | -153,797 | -241,681 | -1,691,767 |
