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 7,049,615, 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 | 7,049,615 | |
| -1 | -7,049,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,049,615.
Example:
1 x 7,049,615 = 7,049,615
and
-1 x -7,049,615 = 7,049,615
Notice both answers equal 7,049,615
With that explanation out of the way, let's continue. Next, we take the number 7,049,615 and divide it by 2:
7,049,615 ÷ 2 = 3,524,807.5
If the quotient is a whole number, then 2 and 3,524,807.5 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 | 7,049,615 | |
| -1 | -7,049,615 |
Now, we try dividing 7,049,615 by 3:
7,049,615 ÷ 3 = 2,349,871.6667
If the quotient is a whole number, then 3 and 2,349,871.6667 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 | 7,049,615 | |
| -1 | -7,049,615 |
Let's try dividing by 4:
7,049,615 ÷ 4 = 1,762,403.75
If the quotient is a whole number, then 4 and 1,762,403.75 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 | 7,049,615 | |
| -1 | 7,049,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 59 | 115 | 295 | 1,039 | 1,357 | 5,195 | 6,785 | 23,897 | 61,301 | 119,485 | 306,505 | 1,409,923 | 7,049,615 |
| -1 | -5 | -23 | -59 | -115 | -295 | -1,039 | -1,357 | -5,195 | -6,785 | -23,897 | -61,301 | -119,485 | -306,505 | -1,409,923 | -7,049,615 |
