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 103,706,885, 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 | 103,706,885 | |
| -1 | -103,706,885 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,706,885.
Example:
1 x 103,706,885 = 103,706,885
and
-1 x -103,706,885 = 103,706,885
Notice both answers equal 103,706,885
With that explanation out of the way, let's continue. Next, we take the number 103,706,885 and divide it by 2:
103,706,885 ÷ 2 = 51,853,442.5
If the quotient is a whole number, then 2 and 51,853,442.5 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 | 103,706,885 | |
| -1 | -103,706,885 |
Now, we try dividing 103,706,885 by 3:
103,706,885 ÷ 3 = 34,568,961.6667
If the quotient is a whole number, then 3 and 34,568,961.6667 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 | 103,706,885 | |
| -1 | -103,706,885 |
Let's try dividing by 4:
103,706,885 ÷ 4 = 25,926,721.25
If the quotient is a whole number, then 4 and 25,926,721.25 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 | 103,706,885 | |
| -1 | 103,706,885 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 23 | 85 | 115 | 391 | 1,955 | 53,047 | 265,235 | 901,799 | 1,220,081 | 4,508,995 | 6,100,405 | 20,741,377 | 103,706,885 |
| -1 | -5 | -17 | -23 | -85 | -115 | -391 | -1,955 | -53,047 | -265,235 | -901,799 | -1,220,081 | -4,508,995 | -6,100,405 | -20,741,377 | -103,706,885 |
