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 23,144,765, 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 | 23,144,765 | |
| -1 | -23,144,765 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,144,765.
Example:
1 x 23,144,765 = 23,144,765
and
-1 x -23,144,765 = 23,144,765
Notice both answers equal 23,144,765
With that explanation out of the way, let's continue. Next, we take the number 23,144,765 and divide it by 2:
23,144,765 ÷ 2 = 11,572,382.5
If the quotient is a whole number, then 2 and 11,572,382.5 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 | 23,144,765 | |
| -1 | -23,144,765 |
Now, we try dividing 23,144,765 by 3:
23,144,765 ÷ 3 = 7,714,921.6667
If the quotient is a whole number, then 3 and 7,714,921.6667 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 | 23,144,765 | |
| -1 | -23,144,765 |
Let's try dividing by 4:
23,144,765 ÷ 4 = 5,786,191.25
If the quotient is a whole number, then 4 and 5,786,191.25 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 | 23,144,765 | |
| -1 | 23,144,765 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 457 | 1,447 | 2,285 | 3,199 | 7,235 | 10,129 | 15,995 | 50,645 | 661,279 | 3,306,395 | 4,628,953 | 23,144,765 |
| -1 | -5 | -7 | -35 | -457 | -1,447 | -2,285 | -3,199 | -7,235 | -10,129 | -15,995 | -50,645 | -661,279 | -3,306,395 | -4,628,953 | -23,144,765 |
