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 3,030,209, 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 | 3,030,209 | |
| -1 | -3,030,209 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,030,209.
Example:
1 x 3,030,209 = 3,030,209
and
-1 x -3,030,209 = 3,030,209
Notice both answers equal 3,030,209
With that explanation out of the way, let's continue. Next, we take the number 3,030,209 and divide it by 2:
3,030,209 ÷ 2 = 1,515,104.5
If the quotient is a whole number, then 2 and 1,515,104.5 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 | 3,030,209 | |
| -1 | -3,030,209 |
Now, we try dividing 3,030,209 by 3:
3,030,209 ÷ 3 = 1,010,069.6667
If the quotient is a whole number, then 3 and 1,010,069.6667 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 | 3,030,209 | |
| -1 | -3,030,209 |
Let's try dividing by 4:
3,030,209 ÷ 4 = 757,552.25
If the quotient is a whole number, then 4 and 757,552.25 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 | 3,030,209 | |
| -1 | 3,030,209 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 49 | 67 | 71 | 91 | 469 | 497 | 637 | 871 | 923 | 3,283 | 3,479 | 4,757 | 6,097 | 6,461 | 33,299 | 42,679 | 45,227 | 61,841 | 233,093 | 432,887 | 3,030,209 |
| -1 | -7 | -13 | -49 | -67 | -71 | -91 | -469 | -497 | -637 | -871 | -923 | -3,283 | -3,479 | -4,757 | -6,097 | -6,461 | -33,299 | -42,679 | -45,227 | -61,841 | -233,093 | -432,887 | -3,030,209 |
