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 23,731,757, 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 | 23,731,757 | |
| -1 | -23,731,757 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,731,757.
Example:
1 x 23,731,757 = 23,731,757
and
-1 x -23,731,757 = 23,731,757
Notice both answers equal 23,731,757
With that explanation out of the way, let's continue. Next, we take the number 23,731,757 and divide it by 2:
23,731,757 ÷ 2 = 11,865,878.5
If the quotient is a whole number, then 2 and 11,865,878.5 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 | 23,731,757 | |
| -1 | -23,731,757 |
Now, we try dividing 23,731,757 by 3:
23,731,757 ÷ 3 = 7,910,585.6667
If the quotient is a whole number, then 3 and 7,910,585.6667 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 | 23,731,757 | |
| -1 | -23,731,757 |
Let's try dividing by 4:
23,731,757 ÷ 4 = 5,932,939.25
If the quotient is a whole number, then 4 and 5,932,939.25 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 | 23,731,757 | |
| -1 | 23,731,757 |
If you did it right, you will end up with this table:
| 1 | 7 | 47 | 53 | 329 | 371 | 1,361 | 2,491 | 9,527 | 17,437 | 63,967 | 72,133 | 447,769 | 504,931 | 3,390,251 | 23,731,757 |
| -1 | -7 | -47 | -53 | -329 | -371 | -1,361 | -2,491 | -9,527 | -17,437 | -63,967 | -72,133 | -447,769 | -504,931 | -3,390,251 | -23,731,757 |
