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 12,003,625, 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 | 12,003,625 | |
| -1 | -12,003,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,003,625.
Example:
1 x 12,003,625 = 12,003,625
and
-1 x -12,003,625 = 12,003,625
Notice both answers equal 12,003,625
With that explanation out of the way, let's continue. Next, we take the number 12,003,625 and divide it by 2:
12,003,625 ÷ 2 = 6,001,812.5
If the quotient is a whole number, then 2 and 6,001,812.5 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 | 12,003,625 | |
| -1 | -12,003,625 |
Now, we try dividing 12,003,625 by 3:
12,003,625 ÷ 3 = 4,001,208.3333
If the quotient is a whole number, then 3 and 4,001,208.3333 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 | 12,003,625 | |
| -1 | -12,003,625 |
Let's try dividing by 4:
12,003,625 ÷ 4 = 3,000,906.25
If the quotient is a whole number, then 4 and 3,000,906.25 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 | 12,003,625 | |
| -1 | 12,003,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 109 | 125 | 545 | 881 | 2,725 | 4,405 | 13,625 | 22,025 | 96,029 | 110,125 | 480,145 | 2,400,725 | 12,003,625 |
| -1 | -5 | -25 | -109 | -125 | -545 | -881 | -2,725 | -4,405 | -13,625 | -22,025 | -96,029 | -110,125 | -480,145 | -2,400,725 | -12,003,625 |
