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 50,315,111, 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 | 50,315,111 | |
| -1 | -50,315,111 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,315,111.
Example:
1 x 50,315,111 = 50,315,111
and
-1 x -50,315,111 = 50,315,111
Notice both answers equal 50,315,111
With that explanation out of the way, let's continue. Next, we take the number 50,315,111 and divide it by 2:
50,315,111 ÷ 2 = 25,157,555.5
If the quotient is a whole number, then 2 and 25,157,555.5 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 | 50,315,111 | |
| -1 | -50,315,111 |
Now, we try dividing 50,315,111 by 3:
50,315,111 ÷ 3 = 16,771,703.6667
If the quotient is a whole number, then 3 and 16,771,703.6667 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 | 50,315,111 | |
| -1 | -50,315,111 |
Let's try dividing by 4:
50,315,111 ÷ 4 = 12,578,777.75
If the quotient is a whole number, then 4 and 12,578,777.75 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 | 50,315,111 | |
| -1 | 50,315,111 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 49 | 77 | 277 | 337 | 539 | 1,939 | 2,359 | 3,047 | 3,707 | 13,573 | 16,513 | 21,329 | 25,949 | 93,349 | 149,303 | 181,643 | 653,443 | 1,026,839 | 4,574,101 | 7,187,873 | 50,315,111 |
| -1 | -7 | -11 | -49 | -77 | -277 | -337 | -539 | -1,939 | -2,359 | -3,047 | -3,707 | -13,573 | -16,513 | -21,329 | -25,949 | -93,349 | -149,303 | -181,643 | -653,443 | -1,026,839 | -4,574,101 | -7,187,873 | -50,315,111 |
