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 241,336,505, 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 | 241,336,505 | |
| -1 | -241,336,505 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 241,336,505.
Example:
1 x 241,336,505 = 241,336,505
and
-1 x -241,336,505 = 241,336,505
Notice both answers equal 241,336,505
With that explanation out of the way, let's continue. Next, we take the number 241,336,505 and divide it by 2:
241,336,505 ÷ 2 = 120,668,252.5
If the quotient is a whole number, then 2 and 120,668,252.5 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 | 241,336,505 | |
| -1 | -241,336,505 |
Now, we try dividing 241,336,505 by 3:
241,336,505 ÷ 3 = 80,445,501.6667
If the quotient is a whole number, then 3 and 80,445,501.6667 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 | 241,336,505 | |
| -1 | -241,336,505 |
Let's try dividing by 4:
241,336,505 ÷ 4 = 60,334,126.25
If the quotient is a whole number, then 4 and 60,334,126.25 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 | 241,336,505 | |
| -1 | 241,336,505 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 151 | 755 | 2,567 | 12,835 | 18,803 | 94,015 | 319,651 | 1,598,255 | 2,839,253 | 14,196,265 | 48,267,301 | 241,336,505 |
| -1 | -5 | -17 | -85 | -151 | -755 | -2,567 | -12,835 | -18,803 | -94,015 | -319,651 | -1,598,255 | -2,839,253 | -14,196,265 | -48,267,301 | -241,336,505 |
