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 543,528,571, 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 | 543,528,571 | |
| -1 | -543,528,571 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 543,528,571.
Example:
1 x 543,528,571 = 543,528,571
and
-1 x -543,528,571 = 543,528,571
Notice both answers equal 543,528,571
With that explanation out of the way, let's continue. Next, we take the number 543,528,571 and divide it by 2:
543,528,571 ÷ 2 = 271,764,285.5
If the quotient is a whole number, then 2 and 271,764,285.5 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 | 543,528,571 | |
| -1 | -543,528,571 |
Now, we try dividing 543,528,571 by 3:
543,528,571 ÷ 3 = 181,176,190.3333
If the quotient is a whole number, then 3 and 181,176,190.3333 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 | 543,528,571 | |
| -1 | -543,528,571 |
Let's try dividing by 4:
543,528,571 ÷ 4 = 135,882,142.75
If the quotient is a whole number, then 4 and 135,882,142.75 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 | 543,528,571 | |
| -1 | 543,528,571 |
If you did it right, you will end up with this table:
| 1 | 23 | 83 | 101 | 1,909 | 2,323 | 2,819 | 8,383 | 64,837 | 192,809 | 233,977 | 284,719 | 5,381,471 | 6,548,537 | 23,631,677 | 543,528,571 |
| -1 | -23 | -83 | -101 | -1,909 | -2,323 | -2,819 | -8,383 | -64,837 | -192,809 | -233,977 | -284,719 | -5,381,471 | -6,548,537 | -23,631,677 | -543,528,571 |
