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 12,926,023, 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 | 12,926,023 | |
| -1 | -12,926,023 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,926,023.
Example:
1 x 12,926,023 = 12,926,023
and
-1 x -12,926,023 = 12,926,023
Notice both answers equal 12,926,023
With that explanation out of the way, let's continue. Next, we take the number 12,926,023 and divide it by 2:
12,926,023 ÷ 2 = 6,463,011.5
If the quotient is a whole number, then 2 and 6,463,011.5 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 | 12,926,023 | |
| -1 | -12,926,023 |
Now, we try dividing 12,926,023 by 3:
12,926,023 ÷ 3 = 4,308,674.3333
If the quotient is a whole number, then 3 and 4,308,674.3333 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 | 12,926,023 | |
| -1 | -12,926,023 |
Let's try dividing by 4:
12,926,023 ÷ 4 = 3,231,505.75
If the quotient is a whole number, then 4 and 3,231,505.75 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 | 12,926,023 | |
| -1 | 12,926,023 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 23 | 209 | 253 | 437 | 2,689 | 4,807 | 29,579 | 51,091 | 61,847 | 562,001 | 680,317 | 1,175,093 | 12,926,023 |
| -1 | -11 | -19 | -23 | -209 | -253 | -437 | -2,689 | -4,807 | -29,579 | -51,091 | -61,847 | -562,001 | -680,317 | -1,175,093 | -12,926,023 |
