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 23,358,137, 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 | 23,358,137 | |
| -1 | -23,358,137 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,358,137.
Example:
1 x 23,358,137 = 23,358,137
and
-1 x -23,358,137 = 23,358,137
Notice both answers equal 23,358,137
With that explanation out of the way, let's continue. Next, we take the number 23,358,137 and divide it by 2:
23,358,137 ÷ 2 = 11,679,068.5
If the quotient is a whole number, then 2 and 11,679,068.5 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 | 23,358,137 | |
| -1 | -23,358,137 |
Now, we try dividing 23,358,137 by 3:
23,358,137 ÷ 3 = 7,786,045.6667
If the quotient is a whole number, then 3 and 7,786,045.6667 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 | 23,358,137 | |
| -1 | -23,358,137 |
Let's try dividing by 4:
23,358,137 ÷ 4 = 5,839,534.25
If the quotient is a whole number, then 4 and 5,839,534.25 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 | 23,358,137 | |
| -1 | 23,358,137 |
If you did it right, you will end up with this table:
| 1 | 11 | 29 | 37 | 319 | 407 | 1,073 | 1,979 | 11,803 | 21,769 | 57,391 | 73,223 | 631,301 | 805,453 | 2,123,467 | 23,358,137 |
| -1 | -11 | -29 | -37 | -319 | -407 | -1,073 | -1,979 | -11,803 | -21,769 | -57,391 | -73,223 | -631,301 | -805,453 | -2,123,467 | -23,358,137 |
