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 12,550,775, 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 | 12,550,775 | |
| -1 | -12,550,775 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,550,775.
Example:
1 x 12,550,775 = 12,550,775
and
-1 x -12,550,775 = 12,550,775
Notice both answers equal 12,550,775
With that explanation out of the way, let's continue. Next, we take the number 12,550,775 and divide it by 2:
12,550,775 ÷ 2 = 6,275,387.5
If the quotient is a whole number, then 2 and 6,275,387.5 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 | 12,550,775 | |
| -1 | -12,550,775 |
Now, we try dividing 12,550,775 by 3:
12,550,775 ÷ 3 = 4,183,591.6667
If the quotient is a whole number, then 3 and 4,183,591.6667 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 | 12,550,775 | |
| -1 | -12,550,775 |
Let's try dividing by 4:
12,550,775 ÷ 4 = 3,137,693.75
If the quotient is a whole number, then 4 and 3,137,693.75 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 | 12,550,775 | |
| -1 | 12,550,775 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 59 | 67 | 127 | 295 | 335 | 635 | 1,475 | 1,675 | 3,175 | 3,953 | 7,493 | 8,509 | 19,765 | 37,465 | 42,545 | 98,825 | 187,325 | 212,725 | 502,031 | 2,510,155 | 12,550,775 |
| -1 | -5 | -25 | -59 | -67 | -127 | -295 | -335 | -635 | -1,475 | -1,675 | -3,175 | -3,953 | -7,493 | -8,509 | -19,765 | -37,465 | -42,545 | -98,825 | -187,325 | -212,725 | -502,031 | -2,510,155 | -12,550,775 |
