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 3,021,445, 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 | 3,021,445 | |
| -1 | -3,021,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,021,445.
Example:
1 x 3,021,445 = 3,021,445
and
-1 x -3,021,445 = 3,021,445
Notice both answers equal 3,021,445
With that explanation out of the way, let's continue. Next, we take the number 3,021,445 and divide it by 2:
3,021,445 ÷ 2 = 1,510,722.5
If the quotient is a whole number, then 2 and 1,510,722.5 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 | 3,021,445 | |
| -1 | -3,021,445 |
Now, we try dividing 3,021,445 by 3:
3,021,445 ÷ 3 = 1,007,148.3333
If the quotient is a whole number, then 3 and 1,007,148.3333 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 | 3,021,445 | |
| -1 | -3,021,445 |
Let's try dividing by 4:
3,021,445 ÷ 4 = 755,361.25
If the quotient is a whole number, then 4 and 755,361.25 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 | 3,021,445 | |
| -1 | 3,021,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 173 | 499 | 865 | 1,211 | 2,495 | 3,493 | 6,055 | 17,465 | 86,327 | 431,635 | 604,289 | 3,021,445 |
| -1 | -5 | -7 | -35 | -173 | -499 | -865 | -1,211 | -2,495 | -3,493 | -6,055 | -17,465 | -86,327 | -431,635 | -604,289 | -3,021,445 |
