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 22,321,325, 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 | 22,321,325 | |
| -1 | -22,321,325 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,321,325.
Example:
1 x 22,321,325 = 22,321,325
and
-1 x -22,321,325 = 22,321,325
Notice both answers equal 22,321,325
With that explanation out of the way, let's continue. Next, we take the number 22,321,325 and divide it by 2:
22,321,325 ÷ 2 = 11,160,662.5
If the quotient is a whole number, then 2 and 11,160,662.5 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 | 22,321,325 | |
| -1 | -22,321,325 |
Now, we try dividing 22,321,325 by 3:
22,321,325 ÷ 3 = 7,440,441.6667
If the quotient is a whole number, then 3 and 7,440,441.6667 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 | 22,321,325 | |
| -1 | -22,321,325 |
Let's try dividing by 4:
22,321,325 ÷ 4 = 5,580,331.25
If the quotient is a whole number, then 4 and 5,580,331.25 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 | 22,321,325 | |
| -1 | 22,321,325 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 65 | 173 | 325 | 397 | 865 | 1,985 | 2,249 | 4,325 | 5,161 | 9,925 | 11,245 | 25,805 | 56,225 | 68,681 | 129,025 | 343,405 | 892,853 | 1,717,025 | 4,464,265 | 22,321,325 |
| -1 | -5 | -13 | -25 | -65 | -173 | -325 | -397 | -865 | -1,985 | -2,249 | -4,325 | -5,161 | -9,925 | -11,245 | -25,805 | -56,225 | -68,681 | -129,025 | -343,405 | -892,853 | -1,717,025 | -4,464,265 | -22,321,325 |
