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 540,444,731, 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 | 540,444,731 | |
| -1 | -540,444,731 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 540,444,731.
Example:
1 x 540,444,731 = 540,444,731
and
-1 x -540,444,731 = 540,444,731
Notice both answers equal 540,444,731
With that explanation out of the way, let's continue. Next, we take the number 540,444,731 and divide it by 2:
540,444,731 ÷ 2 = 270,222,365.5
If the quotient is a whole number, then 2 and 270,222,365.5 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 | 540,444,731 | |
| -1 | -540,444,731 |
Now, we try dividing 540,444,731 by 3:
540,444,731 ÷ 3 = 180,148,243.6667
If the quotient is a whole number, then 3 and 180,148,243.6667 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 | 540,444,731 | |
| -1 | -540,444,731 |
Let's try dividing by 4:
540,444,731 ÷ 4 = 135,111,182.75
If the quotient is a whole number, then 4 and 135,111,182.75 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 | 540,444,731 | |
| -1 | 540,444,731 |
If you did it right, you will end up with this table:
| 1 | 23 | 31 | 271 | 713 | 2,797 | 6,233 | 8,401 | 64,331 | 86,707 | 193,223 | 757,987 | 1,994,261 | 17,433,701 | 23,497,597 | 540,444,731 |
| -1 | -23 | -31 | -271 | -713 | -2,797 | -6,233 | -8,401 | -64,331 | -86,707 | -193,223 | -757,987 | -1,994,261 | -17,433,701 | -23,497,597 | -540,444,731 |
