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 23,440,015, 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 | 23,440,015 | |
| -1 | -23,440,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,440,015.
Example:
1 x 23,440,015 = 23,440,015
and
-1 x -23,440,015 = 23,440,015
Notice both answers equal 23,440,015
With that explanation out of the way, let's continue. Next, we take the number 23,440,015 and divide it by 2:
23,440,015 ÷ 2 = 11,720,007.5
If the quotient is a whole number, then 2 and 11,720,007.5 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 | 23,440,015 | |
| -1 | -23,440,015 |
Now, we try dividing 23,440,015 by 3:
23,440,015 ÷ 3 = 7,813,338.3333
If the quotient is a whole number, then 3 and 7,813,338.3333 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 | 23,440,015 | |
| -1 | -23,440,015 |
Let's try dividing by 4:
23,440,015 ÷ 4 = 5,860,003.75
If the quotient is a whole number, then 4 and 5,860,003.75 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 | 23,440,015 | |
| -1 | 23,440,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 95 | 137 | 685 | 1,801 | 2,603 | 9,005 | 13,015 | 34,219 | 171,095 | 246,737 | 1,233,685 | 4,688,003 | 23,440,015 |
| -1 | -5 | -19 | -95 | -137 | -685 | -1,801 | -2,603 | -9,005 | -13,015 | -34,219 | -171,095 | -246,737 | -1,233,685 | -4,688,003 | -23,440,015 |
