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 272,195, 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 | 272,195 | |
| -1 | -272,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 272,195.
Example:
1 x 272,195 = 272,195
and
-1 x -272,195 = 272,195
Notice both answers equal 272,195
With that explanation out of the way, let's continue. Next, we take the number 272,195 and divide it by 2:
272,195 ÷ 2 = 136,097.5
If the quotient is a whole number, then 2 and 136,097.5 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 | 272,195 | |
| -1 | -272,195 |
Now, we try dividing 272,195 by 3:
272,195 ÷ 3 = 90,731.6667
If the quotient is a whole number, then 3 and 90,731.6667 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 | 272,195 | |
| -1 | -272,195 |
Let's try dividing by 4:
272,195 ÷ 4 = 68,048.75
If the quotient is a whole number, then 4 and 68,048.75 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 | 272,195 | |
| -1 | 272,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 49 | 55 | 77 | 101 | 245 | 385 | 505 | 539 | 707 | 1,111 | 2,695 | 3,535 | 4,949 | 5,555 | 7,777 | 24,745 | 38,885 | 54,439 | 272,195 |
| -1 | -5 | -7 | -11 | -35 | -49 | -55 | -77 | -101 | -245 | -385 | -505 | -539 | -707 | -1,111 | -2,695 | -3,535 | -4,949 | -5,555 | -7,777 | -24,745 | -38,885 | -54,439 | -272,195 |
