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 241,131,247, 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 | 241,131,247 | |
| -1 | -241,131,247 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 241,131,247.
Example:
1 x 241,131,247 = 241,131,247
and
-1 x -241,131,247 = 241,131,247
Notice both answers equal 241,131,247
With that explanation out of the way, let's continue. Next, we take the number 241,131,247 and divide it by 2:
241,131,247 ÷ 2 = 120,565,623.5
If the quotient is a whole number, then 2 and 120,565,623.5 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 | 241,131,247 | |
| -1 | -241,131,247 |
Now, we try dividing 241,131,247 by 3:
241,131,247 ÷ 3 = 80,377,082.3333
If the quotient is a whole number, then 3 and 80,377,082.3333 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 | 241,131,247 | |
| -1 | -241,131,247 |
Let's try dividing by 4:
241,131,247 ÷ 4 = 60,282,811.75
If the quotient is a whole number, then 4 and 60,282,811.75 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 | 241,131,247 | |
| -1 | 241,131,247 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 467 | 3,269 | 4,339 | 7,939 | 30,373 | 55,573 | 73,763 | 516,341 | 2,026,313 | 14,184,191 | 34,447,321 | 241,131,247 |
| -1 | -7 | -17 | -119 | -467 | -3,269 | -4,339 | -7,939 | -30,373 | -55,573 | -73,763 | -516,341 | -2,026,313 | -14,184,191 | -34,447,321 | -241,131,247 |
