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 1,255,045, 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 | 1,255,045 | |
| -1 | -1,255,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,255,045.
Example:
1 x 1,255,045 = 1,255,045
and
-1 x -1,255,045 = 1,255,045
Notice both answers equal 1,255,045
With that explanation out of the way, let's continue. Next, we take the number 1,255,045 and divide it by 2:
1,255,045 ÷ 2 = 627,522.5
If the quotient is a whole number, then 2 and 627,522.5 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 | 1,255,045 | |
| -1 | -1,255,045 |
Now, we try dividing 1,255,045 by 3:
1,255,045 ÷ 3 = 418,348.3333
If the quotient is a whole number, then 3 and 418,348.3333 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 | 1,255,045 | |
| -1 | -1,255,045 |
Let's try dividing by 4:
1,255,045 ÷ 4 = 313,761.25
If the quotient is a whole number, then 4 and 313,761.25 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 | 1,255,045 | |
| -1 | 1,255,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 55 | 95 | 209 | 1,045 | 1,201 | 6,005 | 13,211 | 22,819 | 66,055 | 114,095 | 251,009 | 1,255,045 |
| -1 | -5 | -11 | -19 | -55 | -95 | -209 | -1,045 | -1,201 | -6,005 | -13,211 | -22,819 | -66,055 | -114,095 | -251,009 | -1,255,045 |
