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 542,664,463, 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 | 542,664,463 | |
| -1 | -542,664,463 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 542,664,463.
Example:
1 x 542,664,463 = 542,664,463
and
-1 x -542,664,463 = 542,664,463
Notice both answers equal 542,664,463
With that explanation out of the way, let's continue. Next, we take the number 542,664,463 and divide it by 2:
542,664,463 ÷ 2 = 271,332,231.5
If the quotient is a whole number, then 2 and 271,332,231.5 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 | 542,664,463 | |
| -1 | -542,664,463 |
Now, we try dividing 542,664,463 by 3:
542,664,463 ÷ 3 = 180,888,154.3333
If the quotient is a whole number, then 3 and 180,888,154.3333 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 | 542,664,463 | |
| -1 | -542,664,463 |
Let's try dividing by 4:
542,664,463 ÷ 4 = 135,666,115.75
If the quotient is a whole number, then 4 and 135,666,115.75 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 | 542,664,463 | |
| -1 | 542,664,463 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 97 | 187 | 1,067 | 1,649 | 18,139 | 29,917 | 329,087 | 508,589 | 2,901,949 | 5,594,479 | 31,921,439 | 49,333,133 | 542,664,463 |
| -1 | -11 | -17 | -97 | -187 | -1,067 | -1,649 | -18,139 | -29,917 | -329,087 | -508,589 | -2,901,949 | -5,594,479 | -31,921,439 | -49,333,133 | -542,664,463 |
