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 7,415,111, 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 | 7,415,111 | |
| -1 | -7,415,111 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,415,111.
Example:
1 x 7,415,111 = 7,415,111
and
-1 x -7,415,111 = 7,415,111
Notice both answers equal 7,415,111
With that explanation out of the way, let's continue. Next, we take the number 7,415,111 and divide it by 2:
7,415,111 ÷ 2 = 3,707,555.5
If the quotient is a whole number, then 2 and 3,707,555.5 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 | 7,415,111 | |
| -1 | -7,415,111 |
Now, we try dividing 7,415,111 by 3:
7,415,111 ÷ 3 = 2,471,703.6667
If the quotient is a whole number, then 3 and 2,471,703.6667 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 | 7,415,111 | |
| -1 | -7,415,111 |
Let's try dividing by 4:
7,415,111 ÷ 4 = 1,853,777.75
If the quotient is a whole number, then 4 and 1,853,777.75 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 | 7,415,111 | |
| -1 | 7,415,111 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 19 | 187 | 209 | 323 | 2,087 | 3,553 | 22,957 | 35,479 | 39,653 | 390,269 | 436,183 | 674,101 | 7,415,111 |
| -1 | -11 | -17 | -19 | -187 | -209 | -323 | -2,087 | -3,553 | -22,957 | -35,479 | -39,653 | -390,269 | -436,183 | -674,101 | -7,415,111 |
