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 52,181,519, 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 | 52,181,519 | |
| -1 | -52,181,519 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 52,181,519.
Example:
1 x 52,181,519 = 52,181,519
and
-1 x -52,181,519 = 52,181,519
Notice both answers equal 52,181,519
With that explanation out of the way, let's continue. Next, we take the number 52,181,519 and divide it by 2:
52,181,519 ÷ 2 = 26,090,759.5
If the quotient is a whole number, then 2 and 26,090,759.5 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 | 52,181,519 | |
| -1 | -52,181,519 |
Now, we try dividing 52,181,519 by 3:
52,181,519 ÷ 3 = 17,393,839.6667
If the quotient is a whole number, then 3 and 17,393,839.6667 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 | 52,181,519 | |
| -1 | -52,181,519 |
Let's try dividing by 4:
52,181,519 ÷ 4 = 13,045,379.75
If the quotient is a whole number, then 4 and 13,045,379.75 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 | 52,181,519 | |
| -1 | 52,181,519 |
If you did it right, you will end up with this table:
| 1 | 13 | 83 | 137 | 353 | 1,079 | 1,781 | 4,589 | 11,371 | 29,299 | 48,361 | 147,823 | 380,887 | 628,693 | 4,013,963 | 52,181,519 |
| -1 | -13 | -83 | -137 | -353 | -1,079 | -1,781 | -4,589 | -11,371 | -29,299 | -48,361 | -147,823 | -380,887 | -628,693 | -4,013,963 | -52,181,519 |
