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 22,490,455, 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 | 22,490,455 | |
| -1 | -22,490,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,490,455.
Example:
1 x 22,490,455 = 22,490,455
and
-1 x -22,490,455 = 22,490,455
Notice both answers equal 22,490,455
With that explanation out of the way, let's continue. Next, we take the number 22,490,455 and divide it by 2:
22,490,455 ÷ 2 = 11,245,227.5
If the quotient is a whole number, then 2 and 11,245,227.5 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 | 22,490,455 | |
| -1 | -22,490,455 |
Now, we try dividing 22,490,455 by 3:
22,490,455 ÷ 3 = 7,496,818.3333
If the quotient is a whole number, then 3 and 7,496,818.3333 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 | 22,490,455 | |
| -1 | -22,490,455 |
Let's try dividing by 4:
22,490,455 ÷ 4 = 5,622,613.75
If the quotient is a whole number, then 4 and 5,622,613.75 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 | 22,490,455 | |
| -1 | 22,490,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 179 | 895 | 1,933 | 2,327 | 9,665 | 11,635 | 25,129 | 125,645 | 346,007 | 1,730,035 | 4,498,091 | 22,490,455 |
| -1 | -5 | -13 | -65 | -179 | -895 | -1,933 | -2,327 | -9,665 | -11,635 | -25,129 | -125,645 | -346,007 | -1,730,035 | -4,498,091 | -22,490,455 |
