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 542,174,435, 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 | 542,174,435 | |
| -1 | -542,174,435 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 542,174,435.
Example:
1 x 542,174,435 = 542,174,435
and
-1 x -542,174,435 = 542,174,435
Notice both answers equal 542,174,435
With that explanation out of the way, let's continue. Next, we take the number 542,174,435 and divide it by 2:
542,174,435 ÷ 2 = 271,087,217.5
If the quotient is a whole number, then 2 and 271,087,217.5 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 | 542,174,435 | |
| -1 | -542,174,435 |
Now, we try dividing 542,174,435 by 3:
542,174,435 ÷ 3 = 180,724,811.6667
If the quotient is a whole number, then 3 and 180,724,811.6667 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 | 542,174,435 | |
| -1 | -542,174,435 |
Let's try dividing by 4:
542,174,435 ÷ 4 = 135,543,608.75
If the quotient is a whole number, then 4 and 135,543,608.75 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 | 542,174,435 | |
| -1 | 542,174,435 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 1,861 | 5,297 | 9,305 | 20,471 | 26,485 | 58,267 | 102,355 | 291,335 | 9,857,717 | 49,288,585 | 108,434,887 | 542,174,435 |
| -1 | -5 | -11 | -55 | -1,861 | -5,297 | -9,305 | -20,471 | -26,485 | -58,267 | -102,355 | -291,335 | -9,857,717 | -49,288,585 | -108,434,887 | -542,174,435 |
