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 100,555, 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 | 100,555 | |
| -1 | -100,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,555.
Example:
1 x 100,555 = 100,555
and
-1 x -100,555 = 100,555
Notice both answers equal 100,555
With that explanation out of the way, let's continue. Next, we take the number 100,555 and divide it by 2:
100,555 ÷ 2 = 50,277.5
If the quotient is a whole number, then 2 and 50,277.5 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 | 100,555 | |
| -1 | -100,555 |
Now, we try dividing 100,555 by 3:
100,555 ÷ 3 = 33,518.3333
If the quotient is a whole number, then 3 and 33,518.3333 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 | 100,555 | |
| -1 | -100,555 |
Let's try dividing by 4:
100,555 ÷ 4 = 25,138.75
If the quotient is a whole number, then 4 and 25,138.75 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 | 100,555 | |
| -1 | 100,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 17 | 35 | 65 | 85 | 91 | 119 | 169 | 221 | 455 | 595 | 845 | 1,105 | 1,183 | 1,547 | 2,873 | 5,915 | 7,735 | 14,365 | 20,111 | 100,555 |
| -1 | -5 | -7 | -13 | -17 | -35 | -65 | -85 | -91 | -119 | -169 | -221 | -455 | -595 | -845 | -1,105 | -1,183 | -1,547 | -2,873 | -5,915 | -7,735 | -14,365 | -20,111 | -100,555 |
