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 3,015,047, 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 | 3,015,047 | |
| -1 | -3,015,047 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,015,047.
Example:
1 x 3,015,047 = 3,015,047
and
-1 x -3,015,047 = 3,015,047
Notice both answers equal 3,015,047
With that explanation out of the way, let's continue. Next, we take the number 3,015,047 and divide it by 2:
3,015,047 ÷ 2 = 1,507,523.5
If the quotient is a whole number, then 2 and 1,507,523.5 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 | 3,015,047 | |
| -1 | -3,015,047 |
Now, we try dividing 3,015,047 by 3:
3,015,047 ÷ 3 = 1,005,015.6667
If the quotient is a whole number, then 3 and 1,005,015.6667 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 | 3,015,047 | |
| -1 | -3,015,047 |
Let's try dividing by 4:
3,015,047 ÷ 4 = 753,761.75
If the quotient is a whole number, then 4 and 753,761.75 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 | 3,015,047 | |
| -1 | 3,015,047 |
If you did it right, you will end up with this table:
| 1 | 7 | 23 | 61 | 161 | 307 | 427 | 1,403 | 2,149 | 7,061 | 9,821 | 18,727 | 49,427 | 131,089 | 430,721 | 3,015,047 |
| -1 | -7 | -23 | -61 | -161 | -307 | -427 | -1,403 | -2,149 | -7,061 | -9,821 | -18,727 | -49,427 | -131,089 | -430,721 | -3,015,047 |
