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 541,310,165, 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 | 541,310,165 | |
| -1 | -541,310,165 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 541,310,165.
Example:
1 x 541,310,165 = 541,310,165
and
-1 x -541,310,165 = 541,310,165
Notice both answers equal 541,310,165
With that explanation out of the way, let's continue. Next, we take the number 541,310,165 and divide it by 2:
541,310,165 ÷ 2 = 270,655,082.5
If the quotient is a whole number, then 2 and 270,655,082.5 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 | 541,310,165 | |
| -1 | -541,310,165 |
Now, we try dividing 541,310,165 by 3:
541,310,165 ÷ 3 = 180,436,721.6667
If the quotient is a whole number, then 3 and 180,436,721.6667 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 | 541,310,165 | |
| -1 | -541,310,165 |
Let's try dividing by 4:
541,310,165 ÷ 4 = 135,327,541.25
If the quotient is a whole number, then 4 and 135,327,541.25 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 | 541,310,165 | |
| -1 | 541,310,165 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 3,067 | 3,209 | 15,335 | 16,045 | 33,737 | 35,299 | 168,685 | 176,495 | 9,842,003 | 49,210,015 | 108,262,033 | 541,310,165 |
| -1 | -5 | -11 | -55 | -3,067 | -3,209 | -15,335 | -16,045 | -33,737 | -35,299 | -168,685 | -176,495 | -9,842,003 | -49,210,015 | -108,262,033 | -541,310,165 |
