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 104,021,225, 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 | 104,021,225 | |
| -1 | -104,021,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 104,021,225.
Example:
1 x 104,021,225 = 104,021,225
and
-1 x -104,021,225 = 104,021,225
Notice both answers equal 104,021,225
With that explanation out of the way, let's continue. Next, we take the number 104,021,225 and divide it by 2:
104,021,225 ÷ 2 = 52,010,612.5
If the quotient is a whole number, then 2 and 52,010,612.5 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 | 104,021,225 | |
| -1 | -104,021,225 |
Now, we try dividing 104,021,225 by 3:
104,021,225 ÷ 3 = 34,673,741.6667
If the quotient is a whole number, then 3 and 34,673,741.6667 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 | 104,021,225 | |
| -1 | -104,021,225 |
Let's try dividing by 4:
104,021,225 ÷ 4 = 26,005,306.25
If the quotient is a whole number, then 4 and 26,005,306.25 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 | 104,021,225 | |
| -1 | 104,021,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 25 | 35 | 55 | 77 | 175 | 275 | 385 | 1,925 | 54,037 | 270,185 | 378,259 | 594,407 | 1,350,925 | 1,891,295 | 2,972,035 | 4,160,849 | 9,456,475 | 14,860,175 | 20,804,245 | 104,021,225 |
| -1 | -5 | -7 | -11 | -25 | -35 | -55 | -77 | -175 | -275 | -385 | -1,925 | -54,037 | -270,185 | -378,259 | -594,407 | -1,350,925 | -1,891,295 | -2,972,035 | -4,160,849 | -9,456,475 | -14,860,175 | -20,804,245 | -104,021,225 |
