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 106,330,427, 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 | 106,330,427 | |
| -1 | -106,330,427 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 106,330,427.
Example:
1 x 106,330,427 = 106,330,427
and
-1 x -106,330,427 = 106,330,427
Notice both answers equal 106,330,427
With that explanation out of the way, let's continue. Next, we take the number 106,330,427 and divide it by 2:
106,330,427 ÷ 2 = 53,165,213.5
If the quotient is a whole number, then 2 and 53,165,213.5 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 | 106,330,427 | |
| -1 | -106,330,427 |
Now, we try dividing 106,330,427 by 3:
106,330,427 ÷ 3 = 35,443,475.6667
If the quotient is a whole number, then 3 and 35,443,475.6667 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 | 106,330,427 | |
| -1 | -106,330,427 |
Let's try dividing by 4:
106,330,427 ÷ 4 = 26,582,606.75
If the quotient is a whole number, then 4 and 26,582,606.75 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 | 106,330,427 | |
| -1 | 106,330,427 |
If you did it right, you will end up with this table:
| 1 | 7 | 17 | 119 | 389 | 2,297 | 2,723 | 6,613 | 16,079 | 39,049 | 46,291 | 273,343 | 893,533 | 6,254,731 | 15,190,061 | 106,330,427 |
| -1 | -7 | -17 | -119 | -389 | -2,297 | -2,723 | -6,613 | -16,079 | -39,049 | -46,291 | -273,343 | -893,533 | -6,254,731 | -15,190,061 | -106,330,427 |
