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 540,233,605, 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 | 540,233,605 | |
| -1 | -540,233,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 540,233,605.
Example:
1 x 540,233,605 = 540,233,605
and
-1 x -540,233,605 = 540,233,605
Notice both answers equal 540,233,605
With that explanation out of the way, let's continue. Next, we take the number 540,233,605 and divide it by 2:
540,233,605 ÷ 2 = 270,116,802.5
If the quotient is a whole number, then 2 and 270,116,802.5 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 | 540,233,605 | |
| -1 | -540,233,605 |
Now, we try dividing 540,233,605 by 3:
540,233,605 ÷ 3 = 180,077,868.3333
If the quotient is a whole number, then 3 and 180,077,868.3333 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 | 540,233,605 | |
| -1 | -540,233,605 |
Let's try dividing by 4:
540,233,605 ÷ 4 = 135,058,401.25
If the quotient is a whole number, then 4 and 135,058,401.25 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 | 540,233,605 | |
| -1 | 540,233,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 881 | 4,229 | 4,405 | 21,145 | 25,549 | 122,641 | 127,745 | 613,205 | 3,725,749 | 18,628,745 | 108,046,721 | 540,233,605 |
| -1 | -5 | -29 | -145 | -881 | -4,229 | -4,405 | -21,145 | -25,549 | -122,641 | -127,745 | -613,205 | -3,725,749 | -18,628,745 | -108,046,721 | -540,233,605 |
