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 12,623,699, 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 | 12,623,699 | |
| -1 | -12,623,699 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,623,699.
Example:
1 x 12,623,699 = 12,623,699
and
-1 x -12,623,699 = 12,623,699
Notice both answers equal 12,623,699
With that explanation out of the way, let's continue. Next, we take the number 12,623,699 and divide it by 2:
12,623,699 ÷ 2 = 6,311,849.5
If the quotient is a whole number, then 2 and 6,311,849.5 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 | 12,623,699 | |
| -1 | -12,623,699 |
Now, we try dividing 12,623,699 by 3:
12,623,699 ÷ 3 = 4,207,899.6667
If the quotient is a whole number, then 3 and 4,207,899.6667 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 | 12,623,699 | |
| -1 | -12,623,699 |
Let's try dividing by 4:
12,623,699 ÷ 4 = 3,155,924.75
If the quotient is a whole number, then 4 and 3,155,924.75 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 | 12,623,699 | |
| -1 | 12,623,699 |
If you did it right, you will end up with this table:
| 1 | 11 | 53 | 59 | 367 | 583 | 649 | 3,127 | 4,037 | 19,451 | 21,653 | 34,397 | 213,961 | 238,183 | 1,147,609 | 12,623,699 |
| -1 | -11 | -53 | -59 | -367 | -583 | -649 | -3,127 | -4,037 | -19,451 | -21,653 | -34,397 | -213,961 | -238,183 | -1,147,609 | -12,623,699 |
