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 108,526,271, 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 | 108,526,271 | |
| -1 | -108,526,271 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 108,526,271.
Example:
1 x 108,526,271 = 108,526,271
and
-1 x -108,526,271 = 108,526,271
Notice both answers equal 108,526,271
With that explanation out of the way, let's continue. Next, we take the number 108,526,271 and divide it by 2:
108,526,271 ÷ 2 = 54,263,135.5
If the quotient is a whole number, then 2 and 54,263,135.5 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 | 108,526,271 | |
| -1 | -108,526,271 |
Now, we try dividing 108,526,271 by 3:
108,526,271 ÷ 3 = 36,175,423.6667
If the quotient is a whole number, then 3 and 36,175,423.6667 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 | 108,526,271 | |
| -1 | -108,526,271 |
Let's try dividing by 4:
108,526,271 ÷ 4 = 27,131,567.75
If the quotient is a whole number, then 4 and 27,131,567.75 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 | 108,526,271 | |
| -1 | 108,526,271 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 379 | 2,153 | 2,653 | 7,201 | 15,071 | 40,907 | 50,407 | 286,349 | 815,987 | 5,711,909 | 15,503,753 | 108,526,271 |
| -1 | -7 | -19 | -133 | -379 | -2,153 | -2,653 | -7,201 | -15,071 | -40,907 | -50,407 | -286,349 | -815,987 | -5,711,909 | -15,503,753 | -108,526,271 |
