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 3,073,889, 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 | 3,073,889 | |
| -1 | -3,073,889 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 3,073,889.
Example:
1 x 3,073,889 = 3,073,889
and
-1 x -3,073,889 = 3,073,889
Notice both answers equal 3,073,889
With that explanation out of the way, let's continue. Next, we take the number 3,073,889 and divide it by 2:
3,073,889 ÷ 2 = 1,536,944.5
If the quotient is a whole number, then 2 and 1,536,944.5 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 | 3,073,889 | |
| -1 | -3,073,889 |
Now, we try dividing 3,073,889 by 3:
3,073,889 ÷ 3 = 1,024,629.6667
If the quotient is a whole number, then 3 and 1,024,629.6667 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 | 3,073,889 | |
| -1 | -3,073,889 |
Let's try dividing by 4:
3,073,889 ÷ 4 = 768,472.25
If the quotient is a whole number, then 4 and 768,472.25 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 | 3,073,889 | |
| -1 | 3,073,889 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 17 | 91 | 119 | 221 | 1,547 | 1,987 | 13,909 | 25,831 | 33,779 | 180,817 | 236,453 | 439,127 | 3,073,889 |
| -1 | -7 | -13 | -17 | -91 | -119 | -221 | -1,547 | -1,987 | -13,909 | -25,831 | -33,779 | -180,817 | -236,453 | -439,127 | -3,073,889 |
