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 12,656,347, 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 | 12,656,347 | |
| -1 | -12,656,347 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,656,347.
Example:
1 x 12,656,347 = 12,656,347
and
-1 x -12,656,347 = 12,656,347
Notice both answers equal 12,656,347
With that explanation out of the way, let's continue. Next, we take the number 12,656,347 and divide it by 2:
12,656,347 ÷ 2 = 6,328,173.5
If the quotient is a whole number, then 2 and 6,328,173.5 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 | 12,656,347 | |
| -1 | -12,656,347 |
Now, we try dividing 12,656,347 by 3:
12,656,347 ÷ 3 = 4,218,782.3333
If the quotient is a whole number, then 3 and 4,218,782.3333 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 | 12,656,347 | |
| -1 | -12,656,347 |
Let's try dividing by 4:
12,656,347 ÷ 4 = 3,164,086.75
If the quotient is a whole number, then 4 and 3,164,086.75 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 | 12,656,347 | |
| -1 | 12,656,347 |
If you did it right, you will end up with this table:
| 1 | 11 | 17 | 53 | 187 | 583 | 901 | 1,277 | 9,911 | 14,047 | 21,709 | 67,681 | 238,799 | 744,491 | 1,150,577 | 12,656,347 |
| -1 | -11 | -17 | -53 | -187 | -583 | -901 | -1,277 | -9,911 | -14,047 | -21,709 | -67,681 | -238,799 | -744,491 | -1,150,577 | -12,656,347 |
