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 103,005,859, 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 | 103,005,859 | |
| -1 | -103,005,859 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,005,859.
Example:
1 x 103,005,859 = 103,005,859
and
-1 x -103,005,859 = 103,005,859
Notice both answers equal 103,005,859
With that explanation out of the way, let's continue. Next, we take the number 103,005,859 and divide it by 2:
103,005,859 ÷ 2 = 51,502,929.5
If the quotient is a whole number, then 2 and 51,502,929.5 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 | 103,005,859 | |
| -1 | -103,005,859 |
Now, we try dividing 103,005,859 by 3:
103,005,859 ÷ 3 = 34,335,286.3333
If the quotient is a whole number, then 3 and 34,335,286.3333 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 | 103,005,859 | |
| -1 | -103,005,859 |
Let's try dividing by 4:
103,005,859 ÷ 4 = 25,751,464.75
If the quotient is a whole number, then 4 and 25,751,464.75 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 | 103,005,859 | |
| -1 | 103,005,859 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 209 | 541 | 911 | 5,951 | 10,021 | 10,279 | 17,309 | 113,069 | 190,399 | 492,851 | 5,421,361 | 9,364,169 | 103,005,859 |
| -1 | -11 | -19 | -209 | -541 | -911 | -5,951 | -10,021 | -10,279 | -17,309 | -113,069 | -190,399 | -492,851 | -5,421,361 | -9,364,169 | -103,005,859 |
