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 99,275, 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 | 99,275 | |
| -1 | -99,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 99,275.
Example:
1 x 99,275 = 99,275
and
-1 x -99,275 = 99,275
Notice both answers equal 99,275
With that explanation out of the way, let's continue. Next, we take the number 99,275 and divide it by 2:
99,275 ÷ 2 = 49,637.5
If the quotient is a whole number, then 2 and 49,637.5 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 | 99,275 | |
| -1 | -99,275 |
Now, we try dividing 99,275 by 3:
99,275 ÷ 3 = 33,091.6667
If the quotient is a whole number, then 3 and 33,091.6667 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 | 99,275 | |
| -1 | -99,275 |
Let's try dividing by 4:
99,275 ÷ 4 = 24,818.75
If the quotient is a whole number, then 4 and 24,818.75 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 | 99,275 | |
| -1 | 99,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 19 | 25 | 55 | 95 | 209 | 275 | 361 | 475 | 1,045 | 1,805 | 3,971 | 5,225 | 9,025 | 19,855 | 99,275 |
| -1 | -5 | -11 | -19 | -25 | -55 | -95 | -209 | -275 | -361 | -475 | -1,045 | -1,805 | -3,971 | -5,225 | -9,025 | -19,855 | -99,275 |
