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 548,405, 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 | 548,405 | |
| -1 | -548,405 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 548,405.
Example:
1 x 548,405 = 548,405
and
-1 x -548,405 = 548,405
Notice both answers equal 548,405
With that explanation out of the way, let's continue. Next, we take the number 548,405 and divide it by 2:
548,405 ÷ 2 = 274,202.5
If the quotient is a whole number, then 2 and 274,202.5 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 | 548,405 | |
| -1 | -548,405 |
Now, we try dividing 548,405 by 3:
548,405 ÷ 3 = 182,801.6667
If the quotient is a whole number, then 3 and 182,801.6667 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 | 548,405 | |
| -1 | -548,405 |
Let's try dividing by 4:
548,405 ÷ 4 = 137,101.25
If the quotient is a whole number, then 4 and 137,101.25 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 | 548,405 | |
| -1 | 548,405 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 55 | 59 | 65 | 143 | 169 | 295 | 649 | 715 | 767 | 845 | 1,859 | 3,245 | 3,835 | 8,437 | 9,295 | 9,971 | 42,185 | 49,855 | 109,681 | 548,405 |
| -1 | -5 | -11 | -13 | -55 | -59 | -65 | -143 | -169 | -295 | -649 | -715 | -767 | -845 | -1,859 | -3,245 | -3,835 | -8,437 | -9,295 | -9,971 | -42,185 | -49,855 | -109,681 | -548,405 |
