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 302,863, 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 | 302,863 | |
-1 | -302,863 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,863.
Example:
1 x 302,863 = 302,863
and
-1 x -302,863 = 302,863
Notice both answers equal 302,863
With that explanation out of the way, let's continue. Next, we take the number 302,863 and divide it by 2:
302,863 ÷ 2 = 151,431.5
If the quotient is a whole number, then 2 and 151,431.5 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 | 302,863 | |
-1 | -302,863 |
Now, we try dividing 302,863 by 3:
302,863 ÷ 3 = 100,954.3333
If the quotient is a whole number, then 3 and 100,954.3333 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 | 302,863 | |
-1 | -302,863 |
Let's try dividing by 4:
302,863 ÷ 4 = 75,715.75
If the quotient is a whole number, then 4 and 75,715.75 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 | 302,863 | |
-1 | 302,863 |
If you did it right, you will end up with this table:
1 | 11 | 121 | 2,503 | 27,533 | 302,863 |
-1 | -11 | -121 | -2,503 | -27,533 | -302,863 |
