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 23,389,901, 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 | 23,389,901 | |
| -1 | -23,389,901 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,389,901.
Example:
1 x 23,389,901 = 23,389,901
and
-1 x -23,389,901 = 23,389,901
Notice both answers equal 23,389,901
With that explanation out of the way, let's continue. Next, we take the number 23,389,901 and divide it by 2:
23,389,901 ÷ 2 = 11,694,950.5
If the quotient is a whole number, then 2 and 11,694,950.5 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 | 23,389,901 | |
| -1 | -23,389,901 |
Now, we try dividing 23,389,901 by 3:
23,389,901 ÷ 3 = 7,796,633.6667
If the quotient is a whole number, then 3 and 7,796,633.6667 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 | 23,389,901 | |
| -1 | -23,389,901 |
Let's try dividing by 4:
23,389,901 ÷ 4 = 5,847,475.25
If the quotient is a whole number, then 4 and 5,847,475.25 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 | 23,389,901 | |
| -1 | 23,389,901 |
If you did it right, you will end up with this table:
| 1 | 59 | 61 | 67 | 97 | 3,599 | 3,953 | 4,087 | 5,723 | 5,917 | 6,499 | 241,133 | 349,103 | 383,441 | 396,439 | 23,389,901 |
| -1 | -59 | -61 | -67 | -97 | -3,599 | -3,953 | -4,087 | -5,723 | -5,917 | -6,499 | -241,133 | -349,103 | -383,441 | -396,439 | -23,389,901 |
