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 131,631,563, 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 | 131,631,563 | |
| -1 | -131,631,563 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 131,631,563.
Example:
1 x 131,631,563 = 131,631,563
and
-1 x -131,631,563 = 131,631,563
Notice both answers equal 131,631,563
With that explanation out of the way, let's continue. Next, we take the number 131,631,563 and divide it by 2:
131,631,563 ÷ 2 = 65,815,781.5
If the quotient is a whole number, then 2 and 65,815,781.5 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 | 131,631,563 | |
| -1 | -131,631,563 |
Now, we try dividing 131,631,563 by 3:
131,631,563 ÷ 3 = 43,877,187.6667
If the quotient is a whole number, then 3 and 43,877,187.6667 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 | 131,631,563 | |
| -1 | -131,631,563 |
Let's try dividing by 4:
131,631,563 ÷ 4 = 32,907,890.75
If the quotient is a whole number, then 4 and 32,907,890.75 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 | 131,631,563 | |
| -1 | 131,631,563 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 127 | 133 | 889 | 2,413 | 7,793 | 16,891 | 54,551 | 148,067 | 989,711 | 1,036,469 | 6,927,977 | 18,804,509 | 131,631,563 |
| -1 | -7 | -19 | -127 | -133 | -889 | -2,413 | -7,793 | -16,891 | -54,551 | -148,067 | -989,711 | -1,036,469 | -6,927,977 | -18,804,509 | -131,631,563 |
