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 22,520,005, 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 | 22,520,005 | |
| -1 | -22,520,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,520,005.
Example:
1 x 22,520,005 = 22,520,005
and
-1 x -22,520,005 = 22,520,005
Notice both answers equal 22,520,005
With that explanation out of the way, let's continue. Next, we take the number 22,520,005 and divide it by 2:
22,520,005 ÷ 2 = 11,260,002.5
If the quotient is a whole number, then 2 and 11,260,002.5 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 | 22,520,005 | |
| -1 | -22,520,005 |
Now, we try dividing 22,520,005 by 3:
22,520,005 ÷ 3 = 7,506,668.3333
If the quotient is a whole number, then 3 and 7,506,668.3333 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 | 22,520,005 | |
| -1 | -22,520,005 |
Let's try dividing by 4:
22,520,005 ÷ 4 = 5,630,001.25
If the quotient is a whole number, then 4 and 5,630,001.25 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 | 22,520,005 | |
| -1 | 22,520,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 97 | 295 | 485 | 787 | 3,935 | 5,723 | 28,615 | 46,433 | 76,339 | 232,165 | 381,695 | 4,504,001 | 22,520,005 |
| -1 | -5 | -59 | -97 | -295 | -485 | -787 | -3,935 | -5,723 | -28,615 | -46,433 | -76,339 | -232,165 | -381,695 | -4,504,001 | -22,520,005 |
