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 23,440,865, 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 | 23,440,865 | |
| -1 | -23,440,865 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,440,865.
Example:
1 x 23,440,865 = 23,440,865
and
-1 x -23,440,865 = 23,440,865
Notice both answers equal 23,440,865
With that explanation out of the way, let's continue. Next, we take the number 23,440,865 and divide it by 2:
23,440,865 ÷ 2 = 11,720,432.5
If the quotient is a whole number, then 2 and 11,720,432.5 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 | 23,440,865 | |
| -1 | -23,440,865 |
Now, we try dividing 23,440,865 by 3:
23,440,865 ÷ 3 = 7,813,621.6667
If the quotient is a whole number, then 3 and 7,813,621.6667 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 | 23,440,865 | |
| -1 | -23,440,865 |
Let's try dividing by 4:
23,440,865 ÷ 4 = 5,860,216.25
If the quotient is a whole number, then 4 and 5,860,216.25 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 | 23,440,865 | |
| -1 | 23,440,865 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 49 | 241 | 245 | 397 | 1,205 | 1,687 | 1,985 | 2,779 | 8,435 | 11,809 | 13,895 | 19,453 | 59,045 | 95,677 | 97,265 | 478,385 | 669,739 | 3,348,695 | 4,688,173 | 23,440,865 |
| -1 | -5 | -7 | -35 | -49 | -241 | -245 | -397 | -1,205 | -1,687 | -1,985 | -2,779 | -8,435 | -11,809 | -13,895 | -19,453 | -59,045 | -95,677 | -97,265 | -478,385 | -669,739 | -3,348,695 | -4,688,173 | -23,440,865 |
