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 12,463,507, 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 | 12,463,507 | |
| -1 | -12,463,507 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,463,507.
Example:
1 x 12,463,507 = 12,463,507
and
-1 x -12,463,507 = 12,463,507
Notice both answers equal 12,463,507
With that explanation out of the way, let's continue. Next, we take the number 12,463,507 and divide it by 2:
12,463,507 ÷ 2 = 6,231,753.5
If the quotient is a whole number, then 2 and 6,231,753.5 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 | 12,463,507 | |
| -1 | -12,463,507 |
Now, we try dividing 12,463,507 by 3:
12,463,507 ÷ 3 = 4,154,502.3333
If the quotient is a whole number, then 3 and 4,154,502.3333 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 | 12,463,507 | |
| -1 | -12,463,507 |
Let's try dividing by 4:
12,463,507 ÷ 4 = 3,115,876.75
If the quotient is a whole number, then 4 and 3,115,876.75 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 | 12,463,507 | |
| -1 | 12,463,507 |
If you did it right, you will end up with this table:
| 1 | 7 | 43 | 47 | 301 | 329 | 881 | 2,021 | 6,167 | 14,147 | 37,883 | 41,407 | 265,181 | 289,849 | 1,780,501 | 12,463,507 |
| -1 | -7 | -43 | -47 | -301 | -329 | -881 | -2,021 | -6,167 | -14,147 | -37,883 | -41,407 | -265,181 | -289,849 | -1,780,501 | -12,463,507 |
