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 22,243,145, 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 | 22,243,145 | |
| -1 | -22,243,145 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,243,145.
Example:
1 x 22,243,145 = 22,243,145
and
-1 x -22,243,145 = 22,243,145
Notice both answers equal 22,243,145
With that explanation out of the way, let's continue. Next, we take the number 22,243,145 and divide it by 2:
22,243,145 ÷ 2 = 11,121,572.5
If the quotient is a whole number, then 2 and 11,121,572.5 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 | 22,243,145 | |
| -1 | -22,243,145 |
Now, we try dividing 22,243,145 by 3:
22,243,145 ÷ 3 = 7,414,381.6667
If the quotient is a whole number, then 3 and 7,414,381.6667 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 | 22,243,145 | |
| -1 | -22,243,145 |
Let's try dividing by 4:
22,243,145 ÷ 4 = 5,560,786.25
If the quotient is a whole number, then 4 and 5,560,786.25 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 | 22,243,145 | |
| -1 | 22,243,145 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 131 | 145 | 655 | 1,171 | 3,799 | 5,855 | 18,995 | 33,959 | 153,401 | 169,795 | 767,005 | 4,448,629 | 22,243,145 |
| -1 | -5 | -29 | -131 | -145 | -655 | -1,171 | -3,799 | -5,855 | -18,995 | -33,959 | -153,401 | -169,795 | -767,005 | -4,448,629 | -22,243,145 |
