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 543,545,155, 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 | 543,545,155 | |
| -1 | -543,545,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 543,545,155.
Example:
1 x 543,545,155 = 543,545,155
and
-1 x -543,545,155 = 543,545,155
Notice both answers equal 543,545,155
With that explanation out of the way, let's continue. Next, we take the number 543,545,155 and divide it by 2:
543,545,155 ÷ 2 = 271,772,577.5
If the quotient is a whole number, then 2 and 271,772,577.5 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 | 543,545,155 | |
| -1 | -543,545,155 |
Now, we try dividing 543,545,155 by 3:
543,545,155 ÷ 3 = 181,181,718.3333
If the quotient is a whole number, then 3 and 181,181,718.3333 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 | 543,545,155 | |
| -1 | -543,545,155 |
Let's try dividing by 4:
543,545,155 ÷ 4 = 135,886,288.75
If the quotient is a whole number, then 4 and 135,886,288.75 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 | 543,545,155 | |
| -1 | 543,545,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 215 | 733 | 3,449 | 3,665 | 17,245 | 31,519 | 148,307 | 157,595 | 741,535 | 2,528,117 | 12,640,585 | 108,709,031 | 543,545,155 |
| -1 | -5 | -43 | -215 | -733 | -3,449 | -3,665 | -17,245 | -31,519 | -148,307 | -157,595 | -741,535 | -2,528,117 | -12,640,585 | -108,709,031 | -543,545,155 |
