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 30,841,195, 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 | 30,841,195 | |
| -1 | -30,841,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 30,841,195.
Example:
1 x 30,841,195 = 30,841,195
and
-1 x -30,841,195 = 30,841,195
Notice both answers equal 30,841,195
With that explanation out of the way, let's continue. Next, we take the number 30,841,195 and divide it by 2:
30,841,195 ÷ 2 = 15,420,597.5
If the quotient is a whole number, then 2 and 15,420,597.5 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 | 30,841,195 | |
| -1 | -30,841,195 |
Now, we try dividing 30,841,195 by 3:
30,841,195 ÷ 3 = 10,280,398.3333
If the quotient is a whole number, then 3 and 10,280,398.3333 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 | 30,841,195 | |
| -1 | -30,841,195 |
Let's try dividing by 4:
30,841,195 ÷ 4 = 7,710,298.75
If the quotient is a whole number, then 4 and 7,710,298.75 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 | 30,841,195 | |
| -1 | 30,841,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 35 | 55 | 77 | 385 | 80,107 | 400,535 | 560,749 | 881,177 | 2,803,745 | 4,405,885 | 6,168,239 | 30,841,195 |
| -1 | -5 | -7 | -11 | -35 | -55 | -77 | -385 | -80,107 | -400,535 | -560,749 | -881,177 | -2,803,745 | -4,405,885 | -6,168,239 | -30,841,195 |
