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 241,466,555, 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 | 241,466,555 | |
| -1 | -241,466,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 241,466,555.
Example:
1 x 241,466,555 = 241,466,555
and
-1 x -241,466,555 = 241,466,555
Notice both answers equal 241,466,555
With that explanation out of the way, let's continue. Next, we take the number 241,466,555 and divide it by 2:
241,466,555 ÷ 2 = 120,733,277.5
If the quotient is a whole number, then 2 and 120,733,277.5 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 | 241,466,555 | |
| -1 | -241,466,555 |
Now, we try dividing 241,466,555 by 3:
241,466,555 ÷ 3 = 80,488,851.6667
If the quotient is a whole number, then 3 and 80,488,851.6667 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 | 241,466,555 | |
| -1 | -241,466,555 |
Let's try dividing by 4:
241,466,555 ÷ 4 = 60,366,638.75
If the quotient is a whole number, then 4 and 60,366,638.75 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 | 241,466,555 | |
| -1 | 241,466,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 17 | 55 | 85 | 187 | 935 | 258,253 | 1,291,265 | 2,840,783 | 4,390,301 | 14,203,915 | 21,951,505 | 48,293,311 | 241,466,555 |
| -1 | -5 | -11 | -17 | -55 | -85 | -187 | -935 | -258,253 | -1,291,265 | -2,840,783 | -4,390,301 | -14,203,915 | -21,951,505 | -48,293,311 | -241,466,555 |
