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 23,356,745, 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 | 23,356,745 | |
| -1 | -23,356,745 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,356,745.
Example:
1 x 23,356,745 = 23,356,745
and
-1 x -23,356,745 = 23,356,745
Notice both answers equal 23,356,745
With that explanation out of the way, let's continue. Next, we take the number 23,356,745 and divide it by 2:
23,356,745 ÷ 2 = 11,678,372.5
If the quotient is a whole number, then 2 and 11,678,372.5 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 | 23,356,745 | |
| -1 | -23,356,745 |
Now, we try dividing 23,356,745 by 3:
23,356,745 ÷ 3 = 7,785,581.6667
If the quotient is a whole number, then 3 and 7,785,581.6667 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 | 23,356,745 | |
| -1 | -23,356,745 |
Let's try dividing by 4:
23,356,745 ÷ 4 = 5,839,186.25
If the quotient is a whole number, then 4 and 5,839,186.25 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 | 23,356,745 | |
| -1 | 23,356,745 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 79 | 145 | 395 | 2,039 | 2,291 | 10,195 | 11,455 | 59,131 | 161,081 | 295,655 | 805,405 | 4,671,349 | 23,356,745 |
| -1 | -5 | -29 | -79 | -145 | -395 | -2,039 | -2,291 | -10,195 | -11,455 | -59,131 | -161,081 | -295,655 | -805,405 | -4,671,349 | -23,356,745 |
