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 50,542,225, 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 | 50,542,225 | |
| -1 | -50,542,225 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,542,225.
Example:
1 x 50,542,225 = 50,542,225
and
-1 x -50,542,225 = 50,542,225
Notice both answers equal 50,542,225
With that explanation out of the way, let's continue. Next, we take the number 50,542,225 and divide it by 2:
50,542,225 ÷ 2 = 25,271,112.5
If the quotient is a whole number, then 2 and 25,271,112.5 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 | 50,542,225 | |
| -1 | -50,542,225 |
Now, we try dividing 50,542,225 by 3:
50,542,225 ÷ 3 = 16,847,408.3333
If the quotient is a whole number, then 3 and 16,847,408.3333 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 | 50,542,225 | |
| -1 | -50,542,225 |
Let's try dividing by 4:
50,542,225 ÷ 4 = 12,635,556.25
If the quotient is a whole number, then 4 and 12,635,556.25 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 | 50,542,225 | |
| -1 | 50,542,225 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 79 | 157 | 163 | 395 | 785 | 815 | 1,975 | 3,925 | 4,075 | 12,403 | 12,877 | 25,591 | 62,015 | 64,385 | 127,955 | 310,075 | 321,925 | 639,775 | 2,021,689 | 10,108,445 | 50,542,225 |
| -1 | -5 | -25 | -79 | -157 | -163 | -395 | -785 | -815 | -1,975 | -3,925 | -4,075 | -12,403 | -12,877 | -25,591 | -62,015 | -64,385 | -127,955 | -310,075 | -321,925 | -639,775 | -2,021,689 | -10,108,445 | -50,542,225 |
