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 99,115, 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 | 99,115 | |
-1 | -99,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 99,115.
Example:
1 x 99,115 = 99,115
and
-1 x -99,115 = 99,115
Notice both answers equal 99,115
With that explanation out of the way, let's continue. Next, we take the number 99,115 and divide it by 2:
99,115 ÷ 2 = 49,557.5
If the quotient is a whole number, then 2 and 49,557.5 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 | 99,115 | |
-1 | -99,115 |
Now, we try dividing 99,115 by 3:
99,115 ÷ 3 = 33,038.3333
If the quotient is a whole number, then 3 and 33,038.3333 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 | 99,115 | |
-1 | -99,115 |
Let's try dividing by 4:
99,115 ÷ 4 = 24,778.75
If the quotient is a whole number, then 4 and 24,778.75 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 | 99,115 | |
-1 | 99,115 |
If you did it right, you will end up with this table:
1 | 5 | 43 | 215 | 461 | 2,305 | 19,823 | 99,115 |
-1 | -5 | -43 | -215 | -461 | -2,305 | -19,823 | -99,115 |
