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 22,455,005, 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 | 22,455,005 | |
| -1 | -22,455,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,455,005.
Example:
1 x 22,455,005 = 22,455,005
and
-1 x -22,455,005 = 22,455,005
Notice both answers equal 22,455,005
With that explanation out of the way, let's continue. Next, we take the number 22,455,005 and divide it by 2:
22,455,005 ÷ 2 = 11,227,502.5
If the quotient is a whole number, then 2 and 11,227,502.5 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 | 22,455,005 | |
| -1 | -22,455,005 |
Now, we try dividing 22,455,005 by 3:
22,455,005 ÷ 3 = 7,485,001.6667
If the quotient is a whole number, then 3 and 7,485,001.6667 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 | 22,455,005 | |
| -1 | -22,455,005 |
Let's try dividing by 4:
22,455,005 ÷ 4 = 5,613,751.25
If the quotient is a whole number, then 4 and 5,613,751.25 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 | 22,455,005 | |
| -1 | 22,455,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 31 | 155 | 277 | 523 | 1,385 | 2,615 | 8,587 | 16,213 | 42,935 | 81,065 | 144,871 | 724,355 | 4,491,001 | 22,455,005 |
| -1 | -5 | -31 | -155 | -277 | -523 | -1,385 | -2,615 | -8,587 | -16,213 | -42,935 | -81,065 | -144,871 | -724,355 | -4,491,001 | -22,455,005 |
