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 50,242,445, 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 | 50,242,445 | |
| -1 | -50,242,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,242,445.
Example:
1 x 50,242,445 = 50,242,445
and
-1 x -50,242,445 = 50,242,445
Notice both answers equal 50,242,445
With that explanation out of the way, let's continue. Next, we take the number 50,242,445 and divide it by 2:
50,242,445 ÷ 2 = 25,121,222.5
If the quotient is a whole number, then 2 and 25,121,222.5 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 | 50,242,445 | |
| -1 | -50,242,445 |
Now, we try dividing 50,242,445 by 3:
50,242,445 ÷ 3 = 16,747,481.6667
If the quotient is a whole number, then 3 and 16,747,481.6667 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 | 50,242,445 | |
| -1 | -50,242,445 |
Let's try dividing by 4:
50,242,445 ÷ 4 = 12,560,611.25
If the quotient is a whole number, then 4 and 12,560,611.25 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 | 50,242,445 | |
| -1 | 50,242,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 463 | 1,973 | 2,315 | 5,093 | 9,865 | 21,703 | 25,465 | 108,515 | 913,499 | 4,567,495 | 10,048,489 | 50,242,445 |
| -1 | -5 | -11 | -55 | -463 | -1,973 | -2,315 | -5,093 | -9,865 | -21,703 | -25,465 | -108,515 | -913,499 | -4,567,495 | -10,048,489 | -50,242,445 |
