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 30,932,755, 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 | 30,932,755 | |
| -1 | -30,932,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,932,755.
Example:
1 x 30,932,755 = 30,932,755
and
-1 x -30,932,755 = 30,932,755
Notice both answers equal 30,932,755
With that explanation out of the way, let's continue. Next, we take the number 30,932,755 and divide it by 2:
30,932,755 ÷ 2 = 15,466,377.5
If the quotient is a whole number, then 2 and 15,466,377.5 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 | 30,932,755 | |
| -1 | -30,932,755 |
Now, we try dividing 30,932,755 by 3:
30,932,755 ÷ 3 = 10,310,918.3333
If the quotient is a whole number, then 3 and 10,310,918.3333 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 | 30,932,755 | |
| -1 | -30,932,755 |
Let's try dividing by 4:
30,932,755 ÷ 4 = 7,733,188.75
If the quotient is a whole number, then 4 and 7,733,188.75 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 | 30,932,755 | |
| -1 | 30,932,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 127 | 635 | 889 | 4,445 | 6,959 | 34,795 | 48,713 | 243,565 | 883,793 | 4,418,965 | 6,186,551 | 30,932,755 |
| -1 | -5 | -7 | -35 | -127 | -635 | -889 | -4,445 | -6,959 | -34,795 | -48,713 | -243,565 | -883,793 | -4,418,965 | -6,186,551 | -30,932,755 |
