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 24,664,025, 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 | 24,664,025 | |
| -1 | -24,664,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,664,025.
Example:
1 x 24,664,025 = 24,664,025
and
-1 x -24,664,025 = 24,664,025
Notice both answers equal 24,664,025
With that explanation out of the way, let's continue. Next, we take the number 24,664,025 and divide it by 2:
24,664,025 ÷ 2 = 12,332,012.5
If the quotient is a whole number, then 2 and 12,332,012.5 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 | 24,664,025 | |
| -1 | -24,664,025 |
Now, we try dividing 24,664,025 by 3:
24,664,025 ÷ 3 = 8,221,341.6667
If the quotient is a whole number, then 3 and 8,221,341.6667 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 | 24,664,025 | |
| -1 | -24,664,025 |
Let's try dividing by 4:
24,664,025 ÷ 4 = 6,166,006.25
If the quotient is a whole number, then 4 and 6,166,006.25 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 | 24,664,025 | |
| -1 | 24,664,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 131 | 425 | 443 | 655 | 2,215 | 2,227 | 3,275 | 7,531 | 11,075 | 11,135 | 37,655 | 55,675 | 58,033 | 188,275 | 290,165 | 986,561 | 1,450,825 | 4,932,805 | 24,664,025 |
| -1 | -5 | -17 | -25 | -85 | -131 | -425 | -443 | -655 | -2,215 | -2,227 | -3,275 | -7,531 | -11,075 | -11,135 | -37,655 | -55,675 | -58,033 | -188,275 | -290,165 | -986,561 | -1,450,825 | -4,932,805 | -24,664,025 |
