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 12,024,745, 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 | 12,024,745 | |
| -1 | -12,024,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,024,745.
Example:
1 x 12,024,745 = 12,024,745
and
-1 x -12,024,745 = 12,024,745
Notice both answers equal 12,024,745
With that explanation out of the way, let's continue. Next, we take the number 12,024,745 and divide it by 2:
12,024,745 ÷ 2 = 6,012,372.5
If the quotient is a whole number, then 2 and 6,012,372.5 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 | 12,024,745 | |
| -1 | -12,024,745 |
Now, we try dividing 12,024,745 by 3:
12,024,745 ÷ 3 = 4,008,248.3333
If the quotient is a whole number, then 3 and 4,008,248.3333 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 | 12,024,745 | |
| -1 | -12,024,745 |
Let's try dividing by 4:
12,024,745 ÷ 4 = 3,006,186.25
If the quotient is a whole number, then 4 and 3,006,186.25 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 | 12,024,745 | |
| -1 | 12,024,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 31 | 115 | 155 | 713 | 3,373 | 3,565 | 16,865 | 77,579 | 104,563 | 387,895 | 522,815 | 2,404,949 | 12,024,745 |
| -1 | -5 | -23 | -31 | -115 | -155 | -713 | -3,373 | -3,565 | -16,865 | -77,579 | -104,563 | -387,895 | -522,815 | -2,404,949 | -12,024,745 |
