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 7,219,069, 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 | 7,219,069 | |
| -1 | -7,219,069 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 7,219,069.
Example:
1 x 7,219,069 = 7,219,069
and
-1 x -7,219,069 = 7,219,069
Notice both answers equal 7,219,069
With that explanation out of the way, let's continue. Next, we take the number 7,219,069 and divide it by 2:
7,219,069 ÷ 2 = 3,609,534.5
If the quotient is a whole number, then 2 and 3,609,534.5 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 | 7,219,069 | |
| -1 | -7,219,069 |
Now, we try dividing 7,219,069 by 3:
7,219,069 ÷ 3 = 2,406,356.3333
If the quotient is a whole number, then 3 and 2,406,356.3333 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 | 7,219,069 | |
| -1 | -7,219,069 |
Let's try dividing by 4:
7,219,069 ÷ 4 = 1,804,767.25
If the quotient is a whole number, then 4 and 1,804,767.25 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 | 7,219,069 | |
| -1 | 7,219,069 |
If you did it right, you will end up with this table:
| 1 | 11 | 13 | 19 | 143 | 209 | 247 | 2,657 | 2,717 | 29,227 | 34,541 | 50,483 | 379,951 | 555,313 | 656,279 | 7,219,069 |
| -1 | -11 | -13 | -19 | -143 | -209 | -247 | -2,657 | -2,717 | -29,227 | -34,541 | -50,483 | -379,951 | -555,313 | -656,279 | -7,219,069 |
