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 1,131,545, 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 | 1,131,545 | |
| -1 | -1,131,545 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,131,545.
Example:
1 x 1,131,545 = 1,131,545
and
-1 x -1,131,545 = 1,131,545
Notice both answers equal 1,131,545
With that explanation out of the way, let's continue. Next, we take the number 1,131,545 and divide it by 2:
1,131,545 ÷ 2 = 565,772.5
If the quotient is a whole number, then 2 and 565,772.5 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 | 1,131,545 | |
| -1 | -1,131,545 |
Now, we try dividing 1,131,545 by 3:
1,131,545 ÷ 3 = 377,181.6667
If the quotient is a whole number, then 3 and 377,181.6667 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 | 1,131,545 | |
| -1 | -1,131,545 |
Let's try dividing by 4:
1,131,545 ÷ 4 = 282,886.25
If the quotient is a whole number, then 4 and 282,886.25 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 | 1,131,545 | |
| -1 | 1,131,545 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 43 | 95 | 215 | 277 | 817 | 1,385 | 4,085 | 5,263 | 11,911 | 26,315 | 59,555 | 226,309 | 1,131,545 |
| -1 | -5 | -19 | -43 | -95 | -215 | -277 | -817 | -1,385 | -4,085 | -5,263 | -11,911 | -26,315 | -59,555 | -226,309 | -1,131,545 |
