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 22,310,015, 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 | 22,310,015 | |
| -1 | -22,310,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,310,015.
Example:
1 x 22,310,015 = 22,310,015
and
-1 x -22,310,015 = 22,310,015
Notice both answers equal 22,310,015
With that explanation out of the way, let's continue. Next, we take the number 22,310,015 and divide it by 2:
22,310,015 ÷ 2 = 11,155,007.5
If the quotient is a whole number, then 2 and 11,155,007.5 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 | 22,310,015 | |
| -1 | -22,310,015 |
Now, we try dividing 22,310,015 by 3:
22,310,015 ÷ 3 = 7,436,671.6667
If the quotient is a whole number, then 3 and 7,436,671.6667 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 | 22,310,015 | |
| -1 | -22,310,015 |
Let's try dividing by 4:
22,310,015 ÷ 4 = 5,577,503.75
If the quotient is a whole number, then 4 and 5,577,503.75 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 | 22,310,015 | |
| -1 | 22,310,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 49,033 | 245,165 | 343,231 | 637,429 | 1,716,155 | 3,187,145 | 4,462,003 | 22,310,015 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -49,033 | -245,165 | -343,231 | -637,429 | -1,716,155 | -3,187,145 | -4,462,003 | -22,310,015 |
