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 18,580,463, 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 | 18,580,463 | |
| -1 | -18,580,463 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,580,463.
Example:
1 x 18,580,463 = 18,580,463
and
-1 x -18,580,463 = 18,580,463
Notice both answers equal 18,580,463
With that explanation out of the way, let's continue. Next, we take the number 18,580,463 and divide it by 2:
18,580,463 ÷ 2 = 9,290,231.5
If the quotient is a whole number, then 2 and 9,290,231.5 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 | 18,580,463 | |
| -1 | -18,580,463 |
Now, we try dividing 18,580,463 by 3:
18,580,463 ÷ 3 = 6,193,487.6667
If the quotient is a whole number, then 3 and 6,193,487.6667 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 | 18,580,463 | |
| -1 | -18,580,463 |
Let's try dividing by 4:
18,580,463 ÷ 4 = 4,645,115.75
If the quotient is a whole number, then 4 and 4,645,115.75 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 | 18,580,463 | |
| -1 | 18,580,463 |
If you did it right, you will end up with this table:
| 1 | 11 | 47 | 83 | 433 | 517 | 913 | 3,901 | 4,763 | 20,351 | 35,939 | 42,911 | 223,861 | 395,329 | 1,689,133 | 18,580,463 |
| -1 | -11 | -47 | -83 | -433 | -517 | -913 | -3,901 | -4,763 | -20,351 | -35,939 | -42,911 | -223,861 | -395,329 | -1,689,133 | -18,580,463 |
