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 22,831,765, 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 | 22,831,765 | |
| -1 | -22,831,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 22,831,765.
Example:
1 x 22,831,765 = 22,831,765
and
-1 x -22,831,765 = 22,831,765
Notice both answers equal 22,831,765
With that explanation out of the way, let's continue. Next, we take the number 22,831,765 and divide it by 2:
22,831,765 ÷ 2 = 11,415,882.5
If the quotient is a whole number, then 2 and 11,415,882.5 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 | 22,831,765 | |
| -1 | -22,831,765 |
Now, we try dividing 22,831,765 by 3:
22,831,765 ÷ 3 = 7,610,588.3333
If the quotient is a whole number, then 3 and 7,610,588.3333 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 | 22,831,765 | |
| -1 | -22,831,765 |
Let's try dividing by 4:
22,831,765 ÷ 4 = 5,707,941.25
If the quotient is a whole number, then 4 and 5,707,941.25 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 | 22,831,765 | |
| -1 | 22,831,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 187 | 935 | 24,419 | 122,095 | 268,609 | 415,123 | 1,343,045 | 2,075,615 | 4,566,353 | 22,831,765 |
| -1 | -5 | -11 | -17 | -55 | -85 | -187 | -935 | -24,419 | -122,095 | -268,609 | -415,123 | -1,343,045 | -2,075,615 | -4,566,353 | -22,831,765 |
