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 50,716,505, 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 | 50,716,505 | |
| -1 | -50,716,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,716,505.
Example:
1 x 50,716,505 = 50,716,505
and
-1 x -50,716,505 = 50,716,505
Notice both answers equal 50,716,505
With that explanation out of the way, let's continue. Next, we take the number 50,716,505 and divide it by 2:
50,716,505 ÷ 2 = 25,358,252.5
If the quotient is a whole number, then 2 and 25,358,252.5 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 | 50,716,505 | |
| -1 | -50,716,505 |
Now, we try dividing 50,716,505 by 3:
50,716,505 ÷ 3 = 16,905,501.6667
If the quotient is a whole number, then 3 and 16,905,501.6667 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 | 50,716,505 | |
| -1 | -50,716,505 |
Let's try dividing by 4:
50,716,505 ÷ 4 = 12,679,126.25
If the quotient is a whole number, then 4 and 12,679,126.25 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 | 50,716,505 | |
| -1 | 50,716,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 29 | 35 | 145 | 203 | 841 | 1,015 | 1,723 | 4,205 | 5,887 | 8,615 | 12,061 | 29,435 | 49,967 | 60,305 | 249,835 | 349,769 | 1,449,043 | 1,748,845 | 7,245,215 | 10,143,301 | 50,716,505 |
| -1 | -5 | -7 | -29 | -35 | -145 | -203 | -841 | -1,015 | -1,723 | -4,205 | -5,887 | -8,615 | -12,061 | -29,435 | -49,967 | -60,305 | -249,835 | -349,769 | -1,449,043 | -1,748,845 | -7,245,215 | -10,143,301 | -50,716,505 |
