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 71,995, 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 | 71,995 | |
| -1 | -71,995 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 71,995.
Example:
1 x 71,995 = 71,995
and
-1 x -71,995 = 71,995
Notice both answers equal 71,995
With that explanation out of the way, let's continue. Next, we take the number 71,995 and divide it by 2:
71,995 ÷ 2 = 35,997.5
If the quotient is a whole number, then 2 and 35,997.5 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 | 71,995 | |
| -1 | -71,995 |
Now, we try dividing 71,995 by 3:
71,995 ÷ 3 = 23,998.3333
If the quotient is a whole number, then 3 and 23,998.3333 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 | 71,995 | |
| -1 | -71,995 |
Let's try dividing by 4:
71,995 ÷ 4 = 17,998.75
If the quotient is a whole number, then 4 and 17,998.75 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 | 71,995 | |
| -1 | 71,995 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 17 | 35 | 55 | 77 | 85 | 119 | 121 | 187 | 385 | 595 | 605 | 847 | 935 | 1,309 | 2,057 | 4,235 | 6,545 | 10,285 | 14,399 | 71,995 |
| -1 | -5 | -7 | -11 | -17 | -35 | -55 | -77 | -85 | -119 | -121 | -187 | -385 | -595 | -605 | -847 | -935 | -1,309 | -2,057 | -4,235 | -6,545 | -10,285 | -14,399 | -71,995 |
