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 90,839, 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 | 90,839 | |
-1 | -90,839 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 90,839.
Example:
1 x 90,839 = 90,839
and
-1 x -90,839 = 90,839
Notice both answers equal 90,839
With that explanation out of the way, let's continue. Next, we take the number 90,839 and divide it by 2:
90,839 ÷ 2 = 45,419.5
If the quotient is a whole number, then 2 and 45,419.5 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 | 90,839 | |
-1 | -90,839 |
Now, we try dividing 90,839 by 3:
90,839 ÷ 3 = 30,279.6667
If the quotient is a whole number, then 3 and 30,279.6667 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 | 90,839 | |
-1 | -90,839 |
Let's try dividing by 4:
90,839 ÷ 4 = 22,709.75
If the quotient is a whole number, then 4 and 22,709.75 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 | 90,839 | |
-1 | 90,839 |
If you did it right, you will end up with this table:
1 | 7 | 19 | 133 | 683 | 4,781 | 12,977 | 90,839 |
-1 | -7 | -19 | -133 | -683 | -4,781 | -12,977 | -90,839 |
