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 241,716,625, 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 | 241,716,625 | |
| -1 | -241,716,625 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 241,716,625.
Example:
1 x 241,716,625 = 241,716,625
and
-1 x -241,716,625 = 241,716,625
Notice both answers equal 241,716,625
With that explanation out of the way, let's continue. Next, we take the number 241,716,625 and divide it by 2:
241,716,625 ÷ 2 = 120,858,312.5
If the quotient is a whole number, then 2 and 120,858,312.5 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 | 241,716,625 | |
| -1 | -241,716,625 |
Now, we try dividing 241,716,625 by 3:
241,716,625 ÷ 3 = 80,572,208.3333
If the quotient is a whole number, then 3 and 80,572,208.3333 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 | 241,716,625 | |
| -1 | -241,716,625 |
Let's try dividing by 4:
241,716,625 ÷ 4 = 60,429,156.25
If the quotient is a whole number, then 4 and 60,429,156.25 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 | 241,716,625 | |
| -1 | 241,716,625 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 25 | 85 | 125 | 425 | 2,125 | 113,749 | 568,745 | 1,933,733 | 2,843,725 | 9,668,665 | 14,218,625 | 48,343,325 | 241,716,625 |
| -1 | -5 | -17 | -25 | -85 | -125 | -425 | -2,125 | -113,749 | -568,745 | -1,933,733 | -2,843,725 | -9,668,665 | -14,218,625 | -48,343,325 | -241,716,625 |
