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 18,594,037, 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 | 18,594,037 | |
| -1 | -18,594,037 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,594,037.
Example:
1 x 18,594,037 = 18,594,037
and
-1 x -18,594,037 = 18,594,037
Notice both answers equal 18,594,037
With that explanation out of the way, let's continue. Next, we take the number 18,594,037 and divide it by 2:
18,594,037 ÷ 2 = 9,297,018.5
If the quotient is a whole number, then 2 and 9,297,018.5 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 | 18,594,037 | |
| -1 | -18,594,037 |
Now, we try dividing 18,594,037 by 3:
18,594,037 ÷ 3 = 6,198,012.3333
If the quotient is a whole number, then 3 and 6,198,012.3333 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 | 18,594,037 | |
| -1 | -18,594,037 |
Let's try dividing by 4:
18,594,037 ÷ 4 = 4,648,509.25
If the quotient is a whole number, then 4 and 4,648,509.25 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 | 18,594,037 | |
| -1 | 18,594,037 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 113 | 791 | 1,243 | 2,137 | 8,701 | 14,959 | 23,507 | 164,549 | 241,481 | 1,690,367 | 2,656,291 | 18,594,037 |
| -1 | -7 | -11 | -77 | -113 | -791 | -1,243 | -2,137 | -8,701 | -14,959 | -23,507 | -164,549 | -241,481 | -1,690,367 | -2,656,291 | -18,594,037 |
