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 18,834,073, 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 | 18,834,073 | |
| -1 | -18,834,073 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,834,073.
Example:
1 x 18,834,073 = 18,834,073
and
-1 x -18,834,073 = 18,834,073
Notice both answers equal 18,834,073
With that explanation out of the way, let's continue. Next, we take the number 18,834,073 and divide it by 2:
18,834,073 ÷ 2 = 9,417,036.5
If the quotient is a whole number, then 2 and 9,417,036.5 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 | 18,834,073 | |
| -1 | -18,834,073 |
Now, we try dividing 18,834,073 by 3:
18,834,073 ÷ 3 = 6,278,024.3333
If the quotient is a whole number, then 3 and 6,278,024.3333 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 | 18,834,073 | |
| -1 | -18,834,073 |
Let's try dividing by 4:
18,834,073 ÷ 4 = 4,708,518.25
If the quotient is a whole number, then 4 and 4,708,518.25 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 | 18,834,073 | |
| -1 | 18,834,073 |
If you did it right, you will end up with this table:
| 1 | 19 | 37 | 73 | 367 | 703 | 1,387 | 2,701 | 6,973 | 13,579 | 26,791 | 51,319 | 258,001 | 509,029 | 991,267 | 18,834,073 |
| -1 | -19 | -37 | -73 | -367 | -703 | -1,387 | -2,701 | -6,973 | -13,579 | -26,791 | -51,319 | -258,001 | -509,029 | -991,267 | -18,834,073 |
