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 543,153,115, 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 | 543,153,115 | |
| -1 | -543,153,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 543,153,115.
Example:
1 x 543,153,115 = 543,153,115
and
-1 x -543,153,115 = 543,153,115
Notice both answers equal 543,153,115
With that explanation out of the way, let's continue. Next, we take the number 543,153,115 and divide it by 2:
543,153,115 ÷ 2 = 271,576,557.5
If the quotient is a whole number, then 2 and 271,576,557.5 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 | 543,153,115 | |
| -1 | -543,153,115 |
Now, we try dividing 543,153,115 by 3:
543,153,115 ÷ 3 = 181,051,038.3333
If the quotient is a whole number, then 3 and 181,051,038.3333 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 | 543,153,115 | |
| -1 | -543,153,115 |
Let's try dividing by 4:
543,153,115 ÷ 4 = 135,788,278.75
If the quotient is a whole number, then 4 and 135,788,278.75 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 | 543,153,115 | |
| -1 | 543,153,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 227 | 295 | 1,135 | 8,111 | 13,393 | 40,555 | 66,965 | 478,549 | 1,841,197 | 2,392,745 | 9,205,985 | 108,630,623 | 543,153,115 |
| -1 | -5 | -59 | -227 | -295 | -1,135 | -8,111 | -13,393 | -40,555 | -66,965 | -478,549 | -1,841,197 | -2,392,745 | -9,205,985 | -108,630,623 | -543,153,115 |
