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 3,038,119, 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 | 3,038,119 | |
| -1 | -3,038,119 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,038,119.
Example:
1 x 3,038,119 = 3,038,119
and
-1 x -3,038,119 = 3,038,119
Notice both answers equal 3,038,119
With that explanation out of the way, let's continue. Next, we take the number 3,038,119 and divide it by 2:
3,038,119 ÷ 2 = 1,519,059.5
If the quotient is a whole number, then 2 and 1,519,059.5 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 | 3,038,119 | |
| -1 | -3,038,119 |
Now, we try dividing 3,038,119 by 3:
3,038,119 ÷ 3 = 1,012,706.3333
If the quotient is a whole number, then 3 and 1,012,706.3333 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 | 3,038,119 | |
| -1 | -3,038,119 |
Let's try dividing by 4:
3,038,119 ÷ 4 = 759,529.75
If the quotient is a whole number, then 4 and 759,529.75 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 | 3,038,119 | |
| -1 | 3,038,119 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 53 | 133 | 371 | 431 | 1,007 | 3,017 | 7,049 | 8,189 | 22,843 | 57,323 | 159,901 | 434,017 | 3,038,119 |
| -1 | -7 | -19 | -53 | -133 | -371 | -431 | -1,007 | -3,017 | -7,049 | -8,189 | -22,843 | -57,323 | -159,901 | -434,017 | -3,038,119 |
