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 22,630,025, 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 | 22,630,025 | |
| -1 | -22,630,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,630,025.
Example:
1 x 22,630,025 = 22,630,025
and
-1 x -22,630,025 = 22,630,025
Notice both answers equal 22,630,025
With that explanation out of the way, let's continue. Next, we take the number 22,630,025 and divide it by 2:
22,630,025 ÷ 2 = 11,315,012.5
If the quotient is a whole number, then 2 and 11,315,012.5 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 | 22,630,025 | |
| -1 | -22,630,025 |
Now, we try dividing 22,630,025 by 3:
22,630,025 ÷ 3 = 7,543,341.6667
If the quotient is a whole number, then 3 and 7,543,341.6667 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 | 22,630,025 | |
| -1 | -22,630,025 |
Let's try dividing by 4:
22,630,025 ÷ 4 = 5,657,506.25
If the quotient is a whole number, then 4 and 5,657,506.25 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 | 22,630,025 | |
| -1 | 22,630,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 121 | 275 | 605 | 3,025 | 7,481 | 37,405 | 82,291 | 187,025 | 411,455 | 905,201 | 2,057,275 | 4,526,005 | 22,630,025 |
| -1 | -5 | -11 | -25 | -55 | -121 | -275 | -605 | -3,025 | -7,481 | -37,405 | -82,291 | -187,025 | -411,455 | -905,201 | -2,057,275 | -4,526,005 | -22,630,025 |
