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 549,563, 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 | 549,563 | |
-1 | -549,563 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 549,563.
Example:
1 x 549,563 = 549,563
and
-1 x -549,563 = 549,563
Notice both answers equal 549,563
With that explanation out of the way, let's continue. Next, we take the number 549,563 and divide it by 2:
549,563 ÷ 2 = 274,781.5
If the quotient is a whole number, then 2 and 274,781.5 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 | 549,563 | |
-1 | -549,563 |
Now, we try dividing 549,563 by 3:
549,563 ÷ 3 = 183,187.6667
If the quotient is a whole number, then 3 and 183,187.6667 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 | 549,563 | |
-1 | -549,563 |
Let's try dividing by 4:
549,563 ÷ 4 = 137,390.75
If the quotient is a whole number, then 4 and 137,390.75 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 | 549,563 | |
-1 | 549,563 |
If you did it right, you will end up with this table:
1 | 7 | 78,509 | 549,563 |
-1 | -7 | -78,509 | -549,563 |
