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 268,087, 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 | 268,087 | |
-1 | -268,087 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 268,087.
Example:
1 x 268,087 = 268,087
and
-1 x -268,087 = 268,087
Notice both answers equal 268,087
With that explanation out of the way, let's continue. Next, we take the number 268,087 and divide it by 2:
268,087 ÷ 2 = 134,043.5
If the quotient is a whole number, then 2 and 134,043.5 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 | 268,087 | |
-1 | -268,087 |
Now, we try dividing 268,087 by 3:
268,087 ÷ 3 = 89,362.3333
If the quotient is a whole number, then 3 and 89,362.3333 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 | 268,087 | |
-1 | -268,087 |
Let's try dividing by 4:
268,087 ÷ 4 = 67,021.75
If the quotient is a whole number, then 4 and 67,021.75 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 | 268,087 | |
-1 | 268,087 |
If you did it right, you will end up with this table:
1 | 227 | 1,181 | 268,087 |
-1 | -227 | -1,181 | -268,087 |
