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 11,807,425, 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 | 11,807,425 | |
| -1 | -11,807,425 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 11,807,425.
Example:
1 x 11,807,425 = 11,807,425
and
-1 x -11,807,425 = 11,807,425
Notice both answers equal 11,807,425
With that explanation out of the way, let's continue. Next, we take the number 11,807,425 and divide it by 2:
11,807,425 ÷ 2 = 5,903,712.5
If the quotient is a whole number, then 2 and 5,903,712.5 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 | 11,807,425 | |
| -1 | -11,807,425 |
Now, we try dividing 11,807,425 by 3:
11,807,425 ÷ 3 = 3,935,808.3333
If the quotient is a whole number, then 3 and 3,935,808.3333 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 | 11,807,425 | |
| -1 | -11,807,425 |
Let's try dividing by 4:
11,807,425 ÷ 4 = 2,951,856.25
If the quotient is a whole number, then 4 and 2,951,856.25 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 | 11,807,425 | |
| -1 | 11,807,425 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 109 | 175 | 545 | 619 | 763 | 2,725 | 3,095 | 3,815 | 4,333 | 15,475 | 19,075 | 21,665 | 67,471 | 108,325 | 337,355 | 472,297 | 1,686,775 | 2,361,485 | 11,807,425 |
| -1 | -5 | -7 | -25 | -35 | -109 | -175 | -545 | -619 | -763 | -2,725 | -3,095 | -3,815 | -4,333 | -15,475 | -19,075 | -21,665 | -67,471 | -108,325 | -337,355 | -472,297 | -1,686,775 | -2,361,485 | -11,807,425 |
