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 541,776,115, 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 | 541,776,115 | |
| -1 | -541,776,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 541,776,115.
Example:
1 x 541,776,115 = 541,776,115
and
-1 x -541,776,115 = 541,776,115
Notice both answers equal 541,776,115
With that explanation out of the way, let's continue. Next, we take the number 541,776,115 and divide it by 2:
541,776,115 ÷ 2 = 270,888,057.5
If the quotient is a whole number, then 2 and 270,888,057.5 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 | 541,776,115 | |
| -1 | -541,776,115 |
Now, we try dividing 541,776,115 by 3:
541,776,115 ÷ 3 = 180,592,038.3333
If the quotient is a whole number, then 3 and 180,592,038.3333 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 | 541,776,115 | |
| -1 | -541,776,115 |
Let's try dividing by 4:
541,776,115 ÷ 4 = 135,444,028.75
If the quotient is a whole number, then 4 and 135,444,028.75 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 | 541,776,115 | |
| -1 | 541,776,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 145 | 1,871 | 1,997 | 9,355 | 9,985 | 54,259 | 57,913 | 271,295 | 289,565 | 3,736,387 | 18,681,935 | 108,355,223 | 541,776,115 |
| -1 | -5 | -29 | -145 | -1,871 | -1,997 | -9,355 | -9,985 | -54,259 | -57,913 | -271,295 | -289,565 | -3,736,387 | -18,681,935 | -108,355,223 | -541,776,115 |
