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 50,536,291, 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 | 50,536,291 | |
| -1 | -50,536,291 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 50,536,291.
Example:
1 x 50,536,291 = 50,536,291
and
-1 x -50,536,291 = 50,536,291
Notice both answers equal 50,536,291
With that explanation out of the way, let's continue. Next, we take the number 50,536,291 and divide it by 2:
50,536,291 ÷ 2 = 25,268,145.5
If the quotient is a whole number, then 2 and 25,268,145.5 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 | 50,536,291 | |
| -1 | -50,536,291 |
Now, we try dividing 50,536,291 by 3:
50,536,291 ÷ 3 = 16,845,430.3333
If the quotient is a whole number, then 3 and 16,845,430.3333 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 | 50,536,291 | |
| -1 | -50,536,291 |
Let's try dividing by 4:
50,536,291 ÷ 4 = 12,634,072.75
If the quotient is a whole number, then 4 and 12,634,072.75 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 | 50,536,291 | |
| -1 | 50,536,291 |
If you did it right, you will end up with this table:
| 1 | 13 | 17 | 67 | 221 | 871 | 1,139 | 3,413 | 14,807 | 44,369 | 58,021 | 228,671 | 754,273 | 2,972,723 | 3,887,407 | 50,536,291 |
| -1 | -13 | -17 | -67 | -221 | -871 | -1,139 | -3,413 | -14,807 | -44,369 | -58,021 | -228,671 | -754,273 | -2,972,723 | -3,887,407 | -50,536,291 |
