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 55,102,225, 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 | 55,102,225 | |
| -1 | -55,102,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 55,102,225.
Example:
1 x 55,102,225 = 55,102,225
and
-1 x -55,102,225 = 55,102,225
Notice both answers equal 55,102,225
With that explanation out of the way, let's continue. Next, we take the number 55,102,225 and divide it by 2:
55,102,225 ÷ 2 = 27,551,112.5
If the quotient is a whole number, then 2 and 27,551,112.5 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 | 55,102,225 | |
| -1 | -55,102,225 |
Now, we try dividing 55,102,225 by 3:
55,102,225 ÷ 3 = 18,367,408.3333
If the quotient is a whole number, then 3 and 18,367,408.3333 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 | 55,102,225 | |
| -1 | -55,102,225 |
Let's try dividing by 4:
55,102,225 ÷ 4 = 13,775,556.25
If the quotient is a whole number, then 4 and 13,775,556.25 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 | 55,102,225 | |
| -1 | 55,102,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 73 | 109 | 277 | 365 | 545 | 1,385 | 1,825 | 2,725 | 6,925 | 7,957 | 20,221 | 30,193 | 39,785 | 101,105 | 150,965 | 198,925 | 505,525 | 754,825 | 2,204,089 | 11,020,445 | 55,102,225 |
| -1 | -5 | -25 | -73 | -109 | -277 | -365 | -545 | -1,385 | -1,825 | -2,725 | -6,925 | -7,957 | -20,221 | -30,193 | -39,785 | -101,105 | -150,965 | -198,925 | -505,525 | -754,825 | -2,204,089 | -11,020,445 | -55,102,225 |
