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 3,020,269, 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 | 3,020,269 | |
| -1 | -3,020,269 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,020,269.
Example:
1 x 3,020,269 = 3,020,269
and
-1 x -3,020,269 = 3,020,269
Notice both answers equal 3,020,269
With that explanation out of the way, let's continue. Next, we take the number 3,020,269 and divide it by 2:
3,020,269 ÷ 2 = 1,510,134.5
If the quotient is a whole number, then 2 and 1,510,134.5 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 | 3,020,269 | |
| -1 | -3,020,269 |
Now, we try dividing 3,020,269 by 3:
3,020,269 ÷ 3 = 1,006,756.3333
If the quotient is a whole number, then 3 and 1,006,756.3333 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 | 3,020,269 | |
| -1 | -3,020,269 |
Let's try dividing by 4:
3,020,269 ÷ 4 = 755,067.25
If the quotient is a whole number, then 4 and 755,067.25 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 | 3,020,269 | |
| -1 | 3,020,269 |
If you did it right, you will end up with this table:
| 1 | 7 | 59 | 71 | 103 | 413 | 497 | 721 | 4,189 | 6,077 | 7,313 | 29,323 | 42,539 | 51,191 | 431,467 | 3,020,269 |
| -1 | -7 | -59 | -71 | -103 | -413 | -497 | -721 | -4,189 | -6,077 | -7,313 | -29,323 | -42,539 | -51,191 | -431,467 | -3,020,269 |
