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 23,750,285, 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 | 23,750,285 | |
| -1 | -23,750,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 23,750,285.
Example:
1 x 23,750,285 = 23,750,285
and
-1 x -23,750,285 = 23,750,285
Notice both answers equal 23,750,285
With that explanation out of the way, let's continue. Next, we take the number 23,750,285 and divide it by 2:
23,750,285 ÷ 2 = 11,875,142.5
If the quotient is a whole number, then 2 and 11,875,142.5 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 | 23,750,285 | |
| -1 | -23,750,285 |
Now, we try dividing 23,750,285 by 3:
23,750,285 ÷ 3 = 7,916,761.6667
If the quotient is a whole number, then 3 and 7,916,761.6667 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 | 23,750,285 | |
| -1 | -23,750,285 |
Let's try dividing by 4:
23,750,285 ÷ 4 = 5,937,571.25
If the quotient is a whole number, then 4 and 5,937,571.25 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 | 23,750,285 | |
| -1 | 23,750,285 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 19 | 65 | 95 | 247 | 1,235 | 19,231 | 96,155 | 250,003 | 365,389 | 1,250,015 | 1,826,945 | 4,750,057 | 23,750,285 |
| -1 | -5 | -13 | -19 | -65 | -95 | -247 | -1,235 | -19,231 | -96,155 | -250,003 | -365,389 | -1,250,015 | -1,826,945 | -4,750,057 | -23,750,285 |
