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 541,864,741, 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 | 541,864,741 | |
| -1 | -541,864,741 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 541,864,741.
Example:
1 x 541,864,741 = 541,864,741
and
-1 x -541,864,741 = 541,864,741
Notice both answers equal 541,864,741
With that explanation out of the way, let's continue. Next, we take the number 541,864,741 and divide it by 2:
541,864,741 ÷ 2 = 270,932,370.5
If the quotient is a whole number, then 2 and 270,932,370.5 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 | 541,864,741 | |
| -1 | -541,864,741 |
Now, we try dividing 541,864,741 by 3:
541,864,741 ÷ 3 = 180,621,580.3333
If the quotient is a whole number, then 3 and 180,621,580.3333 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 | 541,864,741 | |
| -1 | -541,864,741 |
Let's try dividing by 4:
541,864,741 ÷ 4 = 135,466,185.25
If the quotient is a whole number, then 4 and 135,466,185.25 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 | 541,864,741 | |
| -1 | 541,864,741 |
If you did it right, you will end up with this table:
| 1 | 11 | 37 | 121 | 407 | 1,331 | 4,477 | 11,003 | 49,247 | 121,033 | 407,111 | 1,331,363 | 4,478,221 | 14,644,993 | 49,260,431 | 541,864,741 |
| -1 | -11 | -37 | -121 | -407 | -1,331 | -4,477 | -11,003 | -49,247 | -121,033 | -407,111 | -1,331,363 | -4,478,221 | -14,644,993 | -49,260,431 | -541,864,741 |
