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 18,482,737, 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 | 18,482,737 | |
| -1 | -18,482,737 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,482,737.
Example:
1 x 18,482,737 = 18,482,737
and
-1 x -18,482,737 = 18,482,737
Notice both answers equal 18,482,737
With that explanation out of the way, let's continue. Next, we take the number 18,482,737 and divide it by 2:
18,482,737 ÷ 2 = 9,241,368.5
If the quotient is a whole number, then 2 and 9,241,368.5 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 | 18,482,737 | |
| -1 | -18,482,737 |
Now, we try dividing 18,482,737 by 3:
18,482,737 ÷ 3 = 6,160,912.3333
If the quotient is a whole number, then 3 and 6,160,912.3333 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 | 18,482,737 | |
| -1 | -18,482,737 |
Let's try dividing by 4:
18,482,737 ÷ 4 = 4,620,684.25
If the quotient is a whole number, then 4 and 4,620,684.25 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 | 18,482,737 | |
| -1 | 18,482,737 |
If you did it right, you will end up with this table:
| 1 | 7 | 13 | 91 | 197 | 1,031 | 1,379 | 2,561 | 7,217 | 13,403 | 17,927 | 93,821 | 203,107 | 1,421,749 | 2,640,391 | 18,482,737 |
| -1 | -7 | -13 | -91 | -197 | -1,031 | -1,379 | -2,561 | -7,217 | -13,403 | -17,927 | -93,821 | -203,107 | -1,421,749 | -2,640,391 | -18,482,737 |
