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 24,664,625, 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 | 24,664,625 | |
| -1 | -24,664,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 24,664,625.
Example:
1 x 24,664,625 = 24,664,625
and
-1 x -24,664,625 = 24,664,625
Notice both answers equal 24,664,625
With that explanation out of the way, let's continue. Next, we take the number 24,664,625 and divide it by 2:
24,664,625 ÷ 2 = 12,332,312.5
If the quotient is a whole number, then 2 and 12,332,312.5 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 | 24,664,625 | |
| -1 | -24,664,625 |
Now, we try dividing 24,664,625 by 3:
24,664,625 ÷ 3 = 8,221,541.6667
If the quotient is a whole number, then 3 and 8,221,541.6667 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 | 24,664,625 | |
| -1 | -24,664,625 |
Let's try dividing by 4:
24,664,625 ÷ 4 = 6,166,156.25
If the quotient is a whole number, then 4 and 6,166,156.25 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 | 24,664,625 | |
| -1 | 24,664,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 115 | 125 | 373 | 529 | 575 | 1,865 | 2,645 | 2,875 | 8,579 | 9,325 | 13,225 | 42,895 | 46,625 | 66,125 | 197,317 | 214,475 | 986,585 | 1,072,375 | 4,932,925 | 24,664,625 |
| -1 | -5 | -23 | -25 | -115 | -125 | -373 | -529 | -575 | -1,865 | -2,645 | -2,875 | -8,579 | -9,325 | -13,225 | -42,895 | -46,625 | -66,125 | -197,317 | -214,475 | -986,585 | -1,072,375 | -4,932,925 | -24,664,625 |
