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 22,102,025, 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 | 22,102,025 | |
| -1 | -22,102,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,102,025.
Example:
1 x 22,102,025 = 22,102,025
and
-1 x -22,102,025 = 22,102,025
Notice both answers equal 22,102,025
With that explanation out of the way, let's continue. Next, we take the number 22,102,025 and divide it by 2:
22,102,025 ÷ 2 = 11,051,012.5
If the quotient is a whole number, then 2 and 11,051,012.5 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 | 22,102,025 | |
| -1 | -22,102,025 |
Now, we try dividing 22,102,025 by 3:
22,102,025 ÷ 3 = 7,367,341.6667
If the quotient is a whole number, then 3 and 7,367,341.6667 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 | 22,102,025 | |
| -1 | -22,102,025 |
Let's try dividing by 4:
22,102,025 ÷ 4 = 5,525,506.25
If the quotient is a whole number, then 4 and 5,525,506.25 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 | 22,102,025 | |
| -1 | 22,102,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 179 | 275 | 449 | 895 | 1,969 | 2,245 | 4,475 | 4,939 | 9,845 | 11,225 | 24,695 | 49,225 | 80,371 | 123,475 | 401,855 | 884,081 | 2,009,275 | 4,420,405 | 22,102,025 |
| -1 | -5 | -11 | -25 | -55 | -179 | -275 | -449 | -895 | -1,969 | -2,245 | -4,475 | -4,939 | -9,845 | -11,225 | -24,695 | -49,225 | -80,371 | -123,475 | -401,855 | -884,081 | -2,009,275 | -4,420,405 | -22,102,025 |
