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 106,650,605, 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 | 106,650,605 | |
| -1 | -106,650,605 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 106,650,605.
Example:
1 x 106,650,605 = 106,650,605
and
-1 x -106,650,605 = 106,650,605
Notice both answers equal 106,650,605
With that explanation out of the way, let's continue. Next, we take the number 106,650,605 and divide it by 2:
106,650,605 ÷ 2 = 53,325,302.5
If the quotient is a whole number, then 2 and 53,325,302.5 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 | 106,650,605 | |
| -1 | -106,650,605 |
Now, we try dividing 106,650,605 by 3:
106,650,605 ÷ 3 = 35,550,201.6667
If the quotient is a whole number, then 3 and 35,550,201.6667 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 | 106,650,605 | |
| -1 | -106,650,605 |
Let's try dividing by 4:
106,650,605 ÷ 4 = 26,662,651.25
If the quotient is a whole number, then 4 and 26,662,651.25 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 | 106,650,605 | |
| -1 | 106,650,605 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 619 | 2,027 | 3,095 | 10,135 | 10,523 | 34,459 | 52,615 | 172,295 | 1,254,713 | 6,273,565 | 21,330,121 | 106,650,605 |
| -1 | -5 | -17 | -85 | -619 | -2,027 | -3,095 | -10,135 | -10,523 | -34,459 | -52,615 | -172,295 | -1,254,713 | -6,273,565 | -21,330,121 | -106,650,605 |
