Negative:
-1 x -283
A:
Positive:
1 x 283
Negative:
-1 x -283
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 283, 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 | 283 | |
| -1 | -283 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 283.
Example:
1 x 283 = 283
and
-1 x -283 = 283
Notice both answers equal 283
With that explanation out of the way, let's continue. Next, we take the number 283 and divide it by 2:
283 ÷ 2 = 141.5
If the quotient is a whole number, then 2 and 141.5 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 | 283 | |
| -1 | -283 |
Now, we try dividing 283 by 3:
283 ÷ 3 = 94.3333
If the quotient is a whole number, then 3 and 94.3333 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 | 283 | |
| -1 | -283 |
Let's try dividing by 4:
283 ÷ 4 = 70.75
If the quotient is a whole number, then 4 and 70.75 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 | 283 | |
| -1 | 283 |
If you did it right, you will end up with this table:
| 1 | 283 |
| -1 | -283 |
