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 540,068,659, 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 | 540,068,659 | |
| -1 | -540,068,659 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 540,068,659.
Example:
1 x 540,068,659 = 540,068,659
and
-1 x -540,068,659 = 540,068,659
Notice both answers equal 540,068,659
With that explanation out of the way, let's continue. Next, we take the number 540,068,659 and divide it by 2:
540,068,659 ÷ 2 = 270,034,329.5
If the quotient is a whole number, then 2 and 270,034,329.5 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 | 540,068,659 | |
| -1 | -540,068,659 |
Now, we try dividing 540,068,659 by 3:
540,068,659 ÷ 3 = 180,022,886.3333
If the quotient is a whole number, then 3 and 180,022,886.3333 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 | 540,068,659 | |
| -1 | -540,068,659 |
Let's try dividing by 4:
540,068,659 ÷ 4 = 135,017,164.75
If the quotient is a whole number, then 4 and 135,017,164.75 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 | 540,068,659 | |
| -1 | 540,068,659 |
If you did it right, you will end up with this table:
| 1 | 13 | 137 | 263 | 1,153 | 1,781 | 3,419 | 14,989 | 36,031 | 157,961 | 303,239 | 468,403 | 2,053,493 | 3,942,107 | 41,543,743 | 540,068,659 |
| -1 | -13 | -137 | -263 | -1,153 | -1,781 | -3,419 | -14,989 | -36,031 | -157,961 | -303,239 | -468,403 | -2,053,493 | -3,942,107 | -41,543,743 | -540,068,659 |
