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 7,219,033, 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 | 7,219,033 | |
| -1 | -7,219,033 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,219,033.
Example:
1 x 7,219,033 = 7,219,033
and
-1 x -7,219,033 = 7,219,033
Notice both answers equal 7,219,033
With that explanation out of the way, let's continue. Next, we take the number 7,219,033 and divide it by 2:
7,219,033 ÷ 2 = 3,609,516.5
If the quotient is a whole number, then 2 and 3,609,516.5 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 | 7,219,033 | |
| -1 | -7,219,033 |
Now, we try dividing 7,219,033 by 3:
7,219,033 ÷ 3 = 2,406,344.3333
If the quotient is a whole number, then 3 and 2,406,344.3333 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 | 7,219,033 | |
| -1 | -7,219,033 |
Let's try dividing by 4:
7,219,033 ÷ 4 = 1,804,758.25
If the quotient is a whole number, then 4 and 1,804,758.25 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 | 7,219,033 | |
| -1 | 7,219,033 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 37 | 391 | 499 | 629 | 851 | 8,483 | 11,477 | 14,467 | 18,463 | 195,109 | 313,871 | 424,649 | 7,219,033 |
| -1 | -17 | -23 | -37 | -391 | -499 | -629 | -851 | -8,483 | -11,477 | -14,467 | -18,463 | -195,109 | -313,871 | -424,649 | -7,219,033 |
