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 22,147,685, 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 | 22,147,685 | |
| -1 | -22,147,685 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,147,685.
Example:
1 x 22,147,685 = 22,147,685
and
-1 x -22,147,685 = 22,147,685
Notice both answers equal 22,147,685
With that explanation out of the way, let's continue. Next, we take the number 22,147,685 and divide it by 2:
22,147,685 ÷ 2 = 11,073,842.5
If the quotient is a whole number, then 2 and 11,073,842.5 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 | 22,147,685 | |
| -1 | -22,147,685 |
Now, we try dividing 22,147,685 by 3:
22,147,685 ÷ 3 = 7,382,561.6667
If the quotient is a whole number, then 3 and 7,382,561.6667 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 | 22,147,685 | |
| -1 | -22,147,685 |
Let's try dividing by 4:
22,147,685 ÷ 4 = 5,536,921.25
If the quotient is a whole number, then 4 and 5,536,921.25 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 | 22,147,685 | |
| -1 | 22,147,685 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 37,223 | 186,115 | 260,561 | 632,791 | 1,302,805 | 3,163,955 | 4,429,537 | 22,147,685 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -37,223 | -186,115 | -260,561 | -632,791 | -1,302,805 | -3,163,955 | -4,429,537 | -22,147,685 |
