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 9,124,255, 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 | 9,124,255 | |
| -1 | -9,124,255 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,124,255.
Example:
1 x 9,124,255 = 9,124,255
and
-1 x -9,124,255 = 9,124,255
Notice both answers equal 9,124,255
With that explanation out of the way, let's continue. Next, we take the number 9,124,255 and divide it by 2:
9,124,255 ÷ 2 = 4,562,127.5
If the quotient is a whole number, then 2 and 4,562,127.5 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 | 9,124,255 | |
| -1 | -9,124,255 |
Now, we try dividing 9,124,255 by 3:
9,124,255 ÷ 3 = 3,041,418.3333
If the quotient is a whole number, then 3 and 3,041,418.3333 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 | 9,124,255 | |
| -1 | -9,124,255 |
Let's try dividing by 4:
9,124,255 ÷ 4 = 2,281,063.75
If the quotient is a whole number, then 4 and 2,281,063.75 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 | 9,124,255 | |
| -1 | 9,124,255 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 103 | 515 | 721 | 2,531 | 3,605 | 12,655 | 17,717 | 88,585 | 260,693 | 1,303,465 | 1,824,851 | 9,124,255 |
| -1 | -5 | -7 | -35 | -103 | -515 | -721 | -2,531 | -3,605 | -12,655 | -17,717 | -88,585 | -260,693 | -1,303,465 | -1,824,851 | -9,124,255 |
