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 22,240,225, 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 | 22,240,225 | |
| -1 | -22,240,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,240,225.
Example:
1 x 22,240,225 = 22,240,225
and
-1 x -22,240,225 = 22,240,225
Notice both answers equal 22,240,225
With that explanation out of the way, let's continue. Next, we take the number 22,240,225 and divide it by 2:
22,240,225 ÷ 2 = 11,120,112.5
If the quotient is a whole number, then 2 and 11,120,112.5 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 | 22,240,225 | |
| -1 | -22,240,225 |
Now, we try dividing 22,240,225 by 3:
22,240,225 ÷ 3 = 7,413,408.3333
If the quotient is a whole number, then 3 and 7,413,408.3333 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 | 22,240,225 | |
| -1 | -22,240,225 |
Let's try dividing by 4:
22,240,225 ÷ 4 = 5,560,056.25
If the quotient is a whole number, then 4 and 5,560,056.25 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 | 22,240,225 | |
| -1 | 22,240,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 167 | 175 | 761 | 835 | 1,169 | 3,805 | 4,175 | 5,327 | 5,845 | 19,025 | 26,635 | 29,225 | 127,087 | 133,175 | 635,435 | 889,609 | 3,177,175 | 4,448,045 | 22,240,225 |
| -1 | -5 | -7 | -25 | -35 | -167 | -175 | -761 | -835 | -1,169 | -3,805 | -4,175 | -5,327 | -5,845 | -19,025 | -26,635 | -29,225 | -127,087 | -133,175 | -635,435 | -889,609 | -3,177,175 | -4,448,045 | -22,240,225 |
