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 131,103,005, 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 | 131,103,005 | |
| -1 | -131,103,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 131,103,005.
Example:
1 x 131,103,005 = 131,103,005
and
-1 x -131,103,005 = 131,103,005
Notice both answers equal 131,103,005
With that explanation out of the way, let's continue. Next, we take the number 131,103,005 and divide it by 2:
131,103,005 ÷ 2 = 65,551,502.5
If the quotient is a whole number, then 2 and 65,551,502.5 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 | 131,103,005 | |
| -1 | -131,103,005 |
Now, we try dividing 131,103,005 by 3:
131,103,005 ÷ 3 = 43,701,001.6667
If the quotient is a whole number, then 3 and 43,701,001.6667 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 | 131,103,005 | |
| -1 | -131,103,005 |
Let's try dividing by 4:
131,103,005 ÷ 4 = 32,775,751.25
If the quotient is a whole number, then 4 and 32,775,751.25 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 | 131,103,005 | |
| -1 | 131,103,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 419 | 2,095 | 4,609 | 5,689 | 23,045 | 28,445 | 62,579 | 312,895 | 2,383,691 | 11,918,455 | 26,220,601 | 131,103,005 |
| -1 | -5 | -11 | -55 | -419 | -2,095 | -4,609 | -5,689 | -23,045 | -28,445 | -62,579 | -312,895 | -2,383,691 | -11,918,455 | -26,220,601 | -131,103,005 |
