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 23,742,755, 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 | 23,742,755 | |
| -1 | -23,742,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,742,755.
Example:
1 x 23,742,755 = 23,742,755
and
-1 x -23,742,755 = 23,742,755
Notice both answers equal 23,742,755
With that explanation out of the way, let's continue. Next, we take the number 23,742,755 and divide it by 2:
23,742,755 ÷ 2 = 11,871,377.5
If the quotient is a whole number, then 2 and 11,871,377.5 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 | 23,742,755 | |
| -1 | -23,742,755 |
Now, we try dividing 23,742,755 by 3:
23,742,755 ÷ 3 = 7,914,251.6667
If the quotient is a whole number, then 3 and 7,914,251.6667 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 | 23,742,755 | |
| -1 | -23,742,755 |
Let's try dividing by 4:
23,742,755 ÷ 4 = 5,935,688.75
If the quotient is a whole number, then 4 and 5,935,688.75 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 | 23,742,755 | |
| -1 | 23,742,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 71 | 235 | 355 | 1,423 | 3,337 | 7,115 | 16,685 | 66,881 | 101,033 | 334,405 | 505,165 | 4,748,551 | 23,742,755 |
| -1 | -5 | -47 | -71 | -235 | -355 | -1,423 | -3,337 | -7,115 | -16,685 | -66,881 | -101,033 | -334,405 | -505,165 | -4,748,551 | -23,742,755 |
