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 305,503,415, 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 | 305,503,415 | |
| -1 | -305,503,415 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 305,503,415.
Example:
1 x 305,503,415 = 305,503,415
and
-1 x -305,503,415 = 305,503,415
Notice both answers equal 305,503,415
With that explanation out of the way, let's continue. Next, we take the number 305,503,415 and divide it by 2:
305,503,415 ÷ 2 = 152,751,707.5
If the quotient is a whole number, then 2 and 152,751,707.5 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 | 305,503,415 | |
| -1 | -305,503,415 |
Now, we try dividing 305,503,415 by 3:
305,503,415 ÷ 3 = 101,834,471.6667
If the quotient is a whole number, then 3 and 101,834,471.6667 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 | 305,503,415 | |
| -1 | -305,503,415 |
Let's try dividing by 4:
305,503,415 ÷ 4 = 76,375,853.75
If the quotient is a whole number, then 4 and 76,375,853.75 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 | 305,503,415 | |
| -1 | 305,503,415 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 71 | 355 | 497 | 2,485 | 122,939 | 614,695 | 860,573 | 4,302,865 | 8,728,669 | 43,643,345 | 61,100,683 | 305,503,415 |
| -1 | -5 | -7 | -35 | -71 | -355 | -497 | -2,485 | -122,939 | -614,695 | -860,573 | -4,302,865 | -8,728,669 | -43,643,345 | -61,100,683 | -305,503,415 |
