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 22,630,505, 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 | 22,630,505 | |
| -1 | -22,630,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,630,505.
Example:
1 x 22,630,505 = 22,630,505
and
-1 x -22,630,505 = 22,630,505
Notice both answers equal 22,630,505
With that explanation out of the way, let's continue. Next, we take the number 22,630,505 and divide it by 2:
22,630,505 ÷ 2 = 11,315,252.5
If the quotient is a whole number, then 2 and 11,315,252.5 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 | 22,630,505 | |
| -1 | -22,630,505 |
Now, we try dividing 22,630,505 by 3:
22,630,505 ÷ 3 = 7,543,501.6667
If the quotient is a whole number, then 3 and 7,543,501.6667 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 | 22,630,505 | |
| -1 | -22,630,505 |
Let's try dividing by 4:
22,630,505 ÷ 4 = 5,657,626.25
If the quotient is a whole number, then 4 and 5,657,626.25 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 | 22,630,505 | |
| -1 | 22,630,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 307 | 641 | 1,535 | 3,205 | 7,061 | 14,743 | 35,305 | 73,715 | 196,787 | 983,935 | 4,526,101 | 22,630,505 |
| -1 | -5 | -23 | -115 | -307 | -641 | -1,535 | -3,205 | -7,061 | -14,743 | -35,305 | -73,715 | -196,787 | -983,935 | -4,526,101 | -22,630,505 |
