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 18,497,969, 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 | 18,497,969 | |
| -1 | -18,497,969 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 18,497,969.
Example:
1 x 18,497,969 = 18,497,969
and
-1 x -18,497,969 = 18,497,969
Notice both answers equal 18,497,969
With that explanation out of the way, let's continue. Next, we take the number 18,497,969 and divide it by 2:
18,497,969 ÷ 2 = 9,248,984.5
If the quotient is a whole number, then 2 and 9,248,984.5 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 | 18,497,969 | |
| -1 | -18,497,969 |
Now, we try dividing 18,497,969 by 3:
18,497,969 ÷ 3 = 6,165,989.6667
If the quotient is a whole number, then 3 and 6,165,989.6667 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 | 18,497,969 | |
| -1 | -18,497,969 |
Let's try dividing by 4:
18,497,969 ÷ 4 = 4,624,492.25
If the quotient is a whole number, then 4 and 4,624,492.25 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 | 18,497,969 | |
| -1 | 18,497,969 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 203 | 293 | 311 | 2,051 | 2,177 | 8,497 | 9,019 | 59,479 | 63,133 | 91,123 | 637,861 | 2,642,567 | 18,497,969 |
| -1 | -7 | -29 | -203 | -293 | -311 | -2,051 | -2,177 | -8,497 | -9,019 | -59,479 | -63,133 | -91,123 | -637,861 | -2,642,567 | -18,497,969 |
