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 23,251,529, 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 | 23,251,529 | |
| -1 | -23,251,529 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,251,529.
Example:
1 x 23,251,529 = 23,251,529
and
-1 x -23,251,529 = 23,251,529
Notice both answers equal 23,251,529
With that explanation out of the way, let's continue. Next, we take the number 23,251,529 and divide it by 2:
23,251,529 ÷ 2 = 11,625,764.5
If the quotient is a whole number, then 2 and 11,625,764.5 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 | 23,251,529 | |
| -1 | -23,251,529 |
Now, we try dividing 23,251,529 by 3:
23,251,529 ÷ 3 = 7,750,509.6667
If the quotient is a whole number, then 3 and 7,750,509.6667 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 | 23,251,529 | |
| -1 | -23,251,529 |
Let's try dividing by 4:
23,251,529 ÷ 4 = 5,812,882.25
If the quotient is a whole number, then 4 and 5,812,882.25 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 | 23,251,529 | |
| -1 | 23,251,529 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 49 | 103 | 119 | 271 | 721 | 833 | 1,751 | 1,897 | 4,607 | 5,047 | 12,257 | 13,279 | 27,913 | 32,249 | 85,799 | 195,391 | 225,743 | 474,521 | 1,367,737 | 3,321,647 | 23,251,529 |
| -1 | -7 | -17 | -49 | -103 | -119 | -271 | -721 | -833 | -1,751 | -1,897 | -4,607 | -5,047 | -12,257 | -13,279 | -27,913 | -32,249 | -85,799 | -195,391 | -225,743 | -474,521 | -1,367,737 | -3,321,647 | -23,251,529 |
