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 540,550,351, 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 | 540,550,351 | |
| -1 | -540,550,351 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 540,550,351.
Example:
1 x 540,550,351 = 540,550,351
and
-1 x -540,550,351 = 540,550,351
Notice both answers equal 540,550,351
With that explanation out of the way, let's continue. Next, we take the number 540,550,351 and divide it by 2:
540,550,351 ÷ 2 = 270,275,175.5
If the quotient is a whole number, then 2 and 270,275,175.5 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 | 540,550,351 | |
| -1 | -540,550,351 |
Now, we try dividing 540,550,351 by 3:
540,550,351 ÷ 3 = 180,183,450.3333
If the quotient is a whole number, then 3 and 180,183,450.3333 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 | 540,550,351 | |
| -1 | -540,550,351 |
Let's try dividing by 4:
540,550,351 ÷ 4 = 135,137,587.75
If the quotient is a whole number, then 4 and 135,137,587.75 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 | 540,550,351 | |
| -1 | 540,550,351 |
If you did it right, you will end up with this table:
| 1 | 11 | 137 | 409 | 877 | 1,507 | 4,499 | 9,647 | 56,033 | 120,149 | 358,693 | 616,363 | 1,321,639 | 3,945,623 | 49,140,941 | 540,550,351 |
| -1 | -11 | -137 | -409 | -877 | -1,507 | -4,499 | -9,647 | -56,033 | -120,149 | -358,693 | -616,363 | -1,321,639 | -3,945,623 | -49,140,941 | -540,550,351 |
