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 50,120,125, 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 | 50,120,125 | |
| -1 | -50,120,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,120,125.
Example:
1 x 50,120,125 = 50,120,125
and
-1 x -50,120,125 = 50,120,125
Notice both answers equal 50,120,125
With that explanation out of the way, let's continue. Next, we take the number 50,120,125 and divide it by 2:
50,120,125 ÷ 2 = 25,060,062.5
If the quotient is a whole number, then 2 and 25,060,062.5 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 | 50,120,125 | |
| -1 | -50,120,125 |
Now, we try dividing 50,120,125 by 3:
50,120,125 ÷ 3 = 16,706,708.3333
If the quotient is a whole number, then 3 and 16,706,708.3333 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 | 50,120,125 | |
| -1 | -50,120,125 |
Let's try dividing by 4:
50,120,125 ÷ 4 = 12,530,031.25
If the quotient is a whole number, then 4 and 12,530,031.25 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 | 50,120,125 | |
| -1 | 50,120,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 25 | 55 | 125 | 275 | 1,375 | 36,451 | 182,255 | 400,961 | 911,275 | 2,004,805 | 4,556,375 | 10,024,025 | 50,120,125 |
| -1 | -5 | -11 | -25 | -55 | -125 | -275 | -1,375 | -36,451 | -182,255 | -400,961 | -911,275 | -2,004,805 | -4,556,375 | -10,024,025 | -50,120,125 |
