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 22,505,225, 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 | 22,505,225 | |
| -1 | -22,505,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,505,225.
Example:
1 x 22,505,225 = 22,505,225
and
-1 x -22,505,225 = 22,505,225
Notice both answers equal 22,505,225
With that explanation out of the way, let's continue. Next, we take the number 22,505,225 and divide it by 2:
22,505,225 ÷ 2 = 11,252,612.5
If the quotient is a whole number, then 2 and 11,252,612.5 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 | 22,505,225 | |
| -1 | -22,505,225 |
Now, we try dividing 22,505,225 by 3:
22,505,225 ÷ 3 = 7,501,741.6667
If the quotient is a whole number, then 3 and 7,501,741.6667 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 | 22,505,225 | |
| -1 | -22,505,225 |
Let's try dividing by 4:
22,505,225 ÷ 4 = 5,626,306.25
If the quotient is a whole number, then 4 and 5,626,306.25 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 | 22,505,225 | |
| -1 | 22,505,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 31 | 71 | 155 | 355 | 409 | 775 | 1,775 | 2,045 | 2,201 | 10,225 | 11,005 | 12,679 | 29,039 | 55,025 | 63,395 | 145,195 | 316,975 | 725,975 | 900,209 | 4,501,045 | 22,505,225 |
| -1 | -5 | -25 | -31 | -71 | -155 | -355 | -409 | -775 | -1,775 | -2,045 | -2,201 | -10,225 | -11,005 | -12,679 | -29,039 | -55,025 | -63,395 | -145,195 | -316,975 | -725,975 | -900,209 | -4,501,045 | -22,505,225 |
