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 50,607,245, 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 | 50,607,245 | |
| -1 | -50,607,245 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,607,245.
Example:
1 x 50,607,245 = 50,607,245
and
-1 x -50,607,245 = 50,607,245
Notice both answers equal 50,607,245
With that explanation out of the way, let's continue. Next, we take the number 50,607,245 and divide it by 2:
50,607,245 ÷ 2 = 25,303,622.5
If the quotient is a whole number, then 2 and 25,303,622.5 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 | 50,607,245 | |
| -1 | -50,607,245 |
Now, we try dividing 50,607,245 by 3:
50,607,245 ÷ 3 = 16,869,081.6667
If the quotient is a whole number, then 3 and 16,869,081.6667 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 | 50,607,245 | |
| -1 | -50,607,245 |
Let's try dividing by 4:
50,607,245 ÷ 4 = 12,651,811.25
If the quotient is a whole number, then 4 and 12,651,811.25 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 | 50,607,245 | |
| -1 | 50,607,245 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 23 | 65 | 115 | 299 | 1,495 | 33,851 | 169,255 | 440,063 | 778,573 | 2,200,315 | 3,892,865 | 10,121,449 | 50,607,245 |
| -1 | -5 | -13 | -23 | -65 | -115 | -299 | -1,495 | -33,851 | -169,255 | -440,063 | -778,573 | -2,200,315 | -3,892,865 | -10,121,449 | -50,607,245 |
