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 543,425,623, 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 | 543,425,623 | |
| -1 | -543,425,623 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 543,425,623.
Example:
1 x 543,425,623 = 543,425,623
and
-1 x -543,425,623 = 543,425,623
Notice both answers equal 543,425,623
With that explanation out of the way, let's continue. Next, we take the number 543,425,623 and divide it by 2:
543,425,623 ÷ 2 = 271,712,811.5
If the quotient is a whole number, then 2 and 271,712,811.5 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 | 543,425,623 | |
| -1 | -543,425,623 |
Now, we try dividing 543,425,623 by 3:
543,425,623 ÷ 3 = 181,141,874.3333
If the quotient is a whole number, then 3 and 181,141,874.3333 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 | 543,425,623 | |
| -1 | -543,425,623 |
Let's try dividing by 4:
543,425,623 ÷ 4 = 135,856,405.75
If the quotient is a whole number, then 4 and 135,856,405.75 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 | 543,425,623 | |
| -1 | 543,425,623 |
If you did it right, you will end up with this table:
| 1 | 13 | 23 | 37 | 299 | 481 | 851 | 11,063 | 49,121 | 638,573 | 1,129,783 | 1,817,477 | 14,687,179 | 23,627,201 | 41,801,971 | 543,425,623 |
| -1 | -13 | -23 | -37 | -299 | -481 | -851 | -11,063 | -49,121 | -638,573 | -1,129,783 | -1,817,477 | -14,687,179 | -23,627,201 | -41,801,971 | -543,425,623 |
