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 275,285, 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 | 275,285 | |
-1 | -275,285 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 275,285.
Example:
1 x 275,285 = 275,285
and
-1 x -275,285 = 275,285
Notice both answers equal 275,285
With that explanation out of the way, let's continue. Next, we take the number 275,285 and divide it by 2:
275,285 ÷ 2 = 137,642.5
If the quotient is a whole number, then 2 and 137,642.5 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 | 275,285 | |
-1 | -275,285 |
Now, we try dividing 275,285 by 3:
275,285 ÷ 3 = 91,761.6667
If the quotient is a whole number, then 3 and 91,761.6667 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 | 275,285 | |
-1 | -275,285 |
Let's try dividing by 4:
275,285 ÷ 4 = 68,821.25
If the quotient is a whole number, then 4 and 68,821.25 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 | 275,285 | |
-1 | 275,285 |
If you did it right, you will end up with this table:
1 | 5 | 55,057 | 275,285 |
-1 | -5 | -55,057 | -275,285 |
