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 100,805,735, 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 | 100,805,735 | |
| -1 | -100,805,735 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,805,735.
Example:
1 x 100,805,735 = 100,805,735
and
-1 x -100,805,735 = 100,805,735
Notice both answers equal 100,805,735
With that explanation out of the way, let's continue. Next, we take the number 100,805,735 and divide it by 2:
100,805,735 ÷ 2 = 50,402,867.5
If the quotient is a whole number, then 2 and 50,402,867.5 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 | 100,805,735 | |
| -1 | -100,805,735 |
Now, we try dividing 100,805,735 by 3:
100,805,735 ÷ 3 = 33,601,911.6667
If the quotient is a whole number, then 3 and 33,601,911.6667 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 | 100,805,735 | |
| -1 | -100,805,735 |
Let's try dividing by 4:
100,805,735 ÷ 4 = 25,201,433.75
If the quotient is a whole number, then 4 and 25,201,433.75 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 | 100,805,735 | |
| -1 | 100,805,735 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 53 | 95 | 265 | 1,007 | 5,035 | 20,021 | 100,105 | 380,399 | 1,061,113 | 1,901,995 | 5,305,565 | 20,161,147 | 100,805,735 |
| -1 | -5 | -19 | -53 | -95 | -265 | -1,007 | -5,035 | -20,021 | -100,105 | -380,399 | -1,061,113 | -1,901,995 | -5,305,565 | -20,161,147 | -100,805,735 |
