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 50,245,025, 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 | 50,245,025 | |
| -1 | -50,245,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,245,025.
Example:
1 x 50,245,025 = 50,245,025
and
-1 x -50,245,025 = 50,245,025
Notice both answers equal 50,245,025
With that explanation out of the way, let's continue. Next, we take the number 50,245,025 and divide it by 2:
50,245,025 ÷ 2 = 25,122,512.5
If the quotient is a whole number, then 2 and 25,122,512.5 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 | 50,245,025 | |
| -1 | -50,245,025 |
Now, we try dividing 50,245,025 by 3:
50,245,025 ÷ 3 = 16,748,341.6667
If the quotient is a whole number, then 3 and 16,748,341.6667 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 | 50,245,025 | |
| -1 | -50,245,025 |
Let's try dividing by 4:
50,245,025 ÷ 4 = 12,561,256.25
If the quotient is a whole number, then 4 and 12,561,256.25 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 | 50,245,025 | |
| -1 | 50,245,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 95 | 139 | 475 | 695 | 761 | 2,641 | 3,475 | 3,805 | 13,205 | 14,459 | 19,025 | 66,025 | 72,295 | 105,779 | 361,475 | 528,895 | 2,009,801 | 2,644,475 | 10,049,005 | 50,245,025 |
| -1 | -5 | -19 | -25 | -95 | -139 | -475 | -695 | -761 | -2,641 | -3,475 | -3,805 | -13,205 | -14,459 | -19,025 | -66,025 | -72,295 | -105,779 | -361,475 | -528,895 | -2,009,801 | -2,644,475 | -10,049,005 | -50,245,025 |
