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 12,204,745, 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 | 12,204,745 | |
| -1 | -12,204,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,204,745.
Example:
1 x 12,204,745 = 12,204,745
and
-1 x -12,204,745 = 12,204,745
Notice both answers equal 12,204,745
With that explanation out of the way, let's continue. Next, we take the number 12,204,745 and divide it by 2:
12,204,745 ÷ 2 = 6,102,372.5
If the quotient is a whole number, then 2 and 6,102,372.5 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 | 12,204,745 | |
| -1 | -12,204,745 |
Now, we try dividing 12,204,745 by 3:
12,204,745 ÷ 3 = 4,068,248.3333
If the quotient is a whole number, then 3 and 4,068,248.3333 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 | 12,204,745 | |
| -1 | -12,204,745 |
Let's try dividing by 4:
12,204,745 ÷ 4 = 3,051,186.25
If the quotient is a whole number, then 4 and 3,051,186.25 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 | 12,204,745 | |
| -1 | 12,204,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 19 | 35 | 95 | 133 | 665 | 18,353 | 91,765 | 128,471 | 348,707 | 642,355 | 1,743,535 | 2,440,949 | 12,204,745 |
| -1 | -5 | -7 | -19 | -35 | -95 | -133 | -665 | -18,353 | -91,765 | -128,471 | -348,707 | -642,355 | -1,743,535 | -2,440,949 | -12,204,745 |
