Negative:
-1 x -541
A:
Positive:
1 x 541
Negative:
-1 x -541
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 541, 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 | 541 | |
| -1 | -541 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 541.
Example:
1 x 541 = 541
and
-1 x -541 = 541
Notice both answers equal 541
With that explanation out of the way, let's continue. Next, we take the number 541 and divide it by 2:
541 ÷ 2 = 270.5
If the quotient is a whole number, then 2 and 270.5 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 | 541 | |
| -1 | -541 |
Now, we try dividing 541 by 3:
541 ÷ 3 = 180.3333
If the quotient is a whole number, then 3 and 180.3333 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 | 541 | |
| -1 | -541 |
Let's try dividing by 4:
541 ÷ 4 = 135.25
If the quotient is a whole number, then 4 and 135.25 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 | 541 | |
| -1 | 541 |
If you did it right, you will end up with this table:
| 1 | 541 |
| -1 | -541 |
