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 7,047,215, 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 | 7,047,215 | |
| -1 | -7,047,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,047,215.
Example:
1 x 7,047,215 = 7,047,215
and
-1 x -7,047,215 = 7,047,215
Notice both answers equal 7,047,215
With that explanation out of the way, let's continue. Next, we take the number 7,047,215 and divide it by 2:
7,047,215 ÷ 2 = 3,523,607.5
If the quotient is a whole number, then 2 and 3,523,607.5 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 | 7,047,215 | |
| -1 | -7,047,215 |
Now, we try dividing 7,047,215 by 3:
7,047,215 ÷ 3 = 2,349,071.6667
If the quotient is a whole number, then 3 and 2,349,071.6667 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 | 7,047,215 | |
| -1 | -7,047,215 |
Let's try dividing by 4:
7,047,215 ÷ 4 = 1,761,803.75
If the quotient is a whole number, then 4 and 1,761,803.75 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 | 7,047,215 | |
| -1 | 7,047,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 227 | 887 | 1,135 | 1,589 | 4,435 | 6,209 | 7,945 | 31,045 | 201,349 | 1,006,745 | 1,409,443 | 7,047,215 |
| -1 | -5 | -7 | -35 | -227 | -887 | -1,135 | -1,589 | -4,435 | -6,209 | -7,945 | -31,045 | -201,349 | -1,006,745 | -1,409,443 | -7,047,215 |
