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 3,010,105, 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 | 3,010,105 | |
| -1 | -3,010,105 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,010,105.
Example:
1 x 3,010,105 = 3,010,105
and
-1 x -3,010,105 = 3,010,105
Notice both answers equal 3,010,105
With that explanation out of the way, let's continue. Next, we take the number 3,010,105 and divide it by 2:
3,010,105 ÷ 2 = 1,505,052.5
If the quotient is a whole number, then 2 and 1,505,052.5 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 | 3,010,105 | |
| -1 | -3,010,105 |
Now, we try dividing 3,010,105 by 3:
3,010,105 ÷ 3 = 1,003,368.3333
If the quotient is a whole number, then 3 and 1,003,368.3333 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 | 3,010,105 | |
| -1 | -3,010,105 |
Let's try dividing by 4:
3,010,105 ÷ 4 = 752,526.25
If the quotient is a whole number, then 4 and 752,526.25 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 | 3,010,105 | |
| -1 | 3,010,105 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 35 | 85 | 119 | 595 | 5,059 | 25,295 | 35,413 | 86,003 | 177,065 | 430,015 | 602,021 | 3,010,105 |
| -1 | -5 | -7 | -17 | -35 | -85 | -119 | -595 | -5,059 | -25,295 | -35,413 | -86,003 | -177,065 | -430,015 | -602,021 | -3,010,105 |
