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 1,083,691, 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 | 1,083,691 | |
| -1 | -1,083,691 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,083,691.
Example:
1 x 1,083,691 = 1,083,691
and
-1 x -1,083,691 = 1,083,691
Notice both answers equal 1,083,691
With that explanation out of the way, let's continue. Next, we take the number 1,083,691 and divide it by 2:
1,083,691 ÷ 2 = 541,845.5
If the quotient is a whole number, then 2 and 541,845.5 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 | 1,083,691 | |
| -1 | -1,083,691 |
Now, we try dividing 1,083,691 by 3:
1,083,691 ÷ 3 = 361,230.3333
If the quotient is a whole number, then 3 and 361,230.3333 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 | 1,083,691 | |
| -1 | -1,083,691 |
Let's try dividing by 4:
1,083,691 ÷ 4 = 270,922.75
If the quotient is a whole number, then 4 and 270,922.75 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 | 1,083,691 | |
| -1 | 1,083,691 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 53 | 127 | 161 | 371 | 889 | 1,219 | 2,921 | 6,731 | 8,533 | 20,447 | 47,117 | 154,813 | 1,083,691 |
| -1 | -7 | -23 | -53 | -127 | -161 | -371 | -889 | -1,219 | -2,921 | -6,731 | -8,533 | -20,447 | -47,117 | -154,813 | -1,083,691 |
