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 542,208,559, 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 | 542,208,559 | |
| -1 | -542,208,559 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 542,208,559.
Example:
1 x 542,208,559 = 542,208,559
and
-1 x -542,208,559 = 542,208,559
Notice both answers equal 542,208,559
With that explanation out of the way, let's continue. Next, we take the number 542,208,559 and divide it by 2:
542,208,559 ÷ 2 = 271,104,279.5
If the quotient is a whole number, then 2 and 271,104,279.5 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 | 542,208,559 | |
| -1 | -542,208,559 |
Now, we try dividing 542,208,559 by 3:
542,208,559 ÷ 3 = 180,736,186.3333
If the quotient is a whole number, then 3 and 180,736,186.3333 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 | 542,208,559 | |
| -1 | -542,208,559 |
Let's try dividing by 4:
542,208,559 ÷ 4 = 135,552,139.75
If the quotient is a whole number, then 4 and 135,552,139.75 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 | 542,208,559 | |
| -1 | 542,208,559 |
If you did it right, you will end up with this table:
| 1 | 41 | 89 | 139 | 1,069 | 3,649 | 5,699 | 12,371 | 43,829 | 95,141 | 148,591 | 507,211 | 3,900,781 | 6,092,231 | 13,224,599 | 542,208,559 |
| -1 | -41 | -89 | -139 | -1,069 | -3,649 | -5,699 | -12,371 | -43,829 | -95,141 | -148,591 | -507,211 | -3,900,781 | -6,092,231 | -13,224,599 | -542,208,559 |
