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 549,881, 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 | 549,881 | |
-1 | -549,881 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 549,881.
Example:
1 x 549,881 = 549,881
and
-1 x -549,881 = 549,881
Notice both answers equal 549,881
With that explanation out of the way, let's continue. Next, we take the number 549,881 and divide it by 2:
549,881 ÷ 2 = 274,940.5
If the quotient is a whole number, then 2 and 274,940.5 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 | 549,881 | |
-1 | -549,881 |
Now, we try dividing 549,881 by 3:
549,881 ÷ 3 = 183,293.6667
If the quotient is a whole number, then 3 and 183,293.6667 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 | 549,881 | |
-1 | -549,881 |
Let's try dividing by 4:
549,881 ÷ 4 = 137,470.25
If the quotient is a whole number, then 4 and 137,470.25 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 | 549,881 | |
-1 | 549,881 |
If you did it right, you will end up with this table:
1 | 577 | 953 | 549,881 |
-1 | -577 | -953 | -549,881 |
