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 540,050,251, 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 | 540,050,251 | |
| -1 | -540,050,251 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 540,050,251.
Example:
1 x 540,050,251 = 540,050,251
and
-1 x -540,050,251 = 540,050,251
Notice both answers equal 540,050,251
With that explanation out of the way, let's continue. Next, we take the number 540,050,251 and divide it by 2:
540,050,251 ÷ 2 = 270,025,125.5
If the quotient is a whole number, then 2 and 270,025,125.5 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 | 540,050,251 | |
| -1 | -540,050,251 |
Now, we try dividing 540,050,251 by 3:
540,050,251 ÷ 3 = 180,016,750.3333
If the quotient is a whole number, then 3 and 180,016,750.3333 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 | 540,050,251 | |
| -1 | -540,050,251 |
Let's try dividing by 4:
540,050,251 ÷ 4 = 135,012,562.75
If the quotient is a whole number, then 4 and 135,012,562.75 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 | 540,050,251 | |
| -1 | 540,050,251 |
If you did it right, you will end up with this table:
| 1 | 13 | 131 | 337 | 941 | 1,703 | 4,381 | 12,233 | 44,147 | 123,271 | 317,117 | 573,911 | 1,602,523 | 4,122,521 | 41,542,327 | 540,050,251 |
| -1 | -13 | -131 | -337 | -941 | -1,703 | -4,381 | -12,233 | -44,147 | -123,271 | -317,117 | -573,911 | -1,602,523 | -4,122,521 | -41,542,327 | -540,050,251 |
