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 12,341,215, 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 | 12,341,215 | |
| -1 | -12,341,215 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,341,215.
Example:
1 x 12,341,215 = 12,341,215
and
-1 x -12,341,215 = 12,341,215
Notice both answers equal 12,341,215
With that explanation out of the way, let's continue. Next, we take the number 12,341,215 and divide it by 2:
12,341,215 ÷ 2 = 6,170,607.5
If the quotient is a whole number, then 2 and 6,170,607.5 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 | 12,341,215 | |
| -1 | -12,341,215 |
Now, we try dividing 12,341,215 by 3:
12,341,215 ÷ 3 = 4,113,738.3333
If the quotient is a whole number, then 3 and 4,113,738.3333 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 | 12,341,215 | |
| -1 | -12,341,215 |
Let's try dividing by 4:
12,341,215 ÷ 4 = 3,085,303.75
If the quotient is a whole number, then 4 and 3,085,303.75 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 | 12,341,215 | |
| -1 | 12,341,215 |
If you did it right, you will end up with this table:
| 1 | 5 | 43 | 61 | 215 | 305 | 941 | 2,623 | 4,705 | 13,115 | 40,463 | 57,401 | 202,315 | 287,005 | 2,468,243 | 12,341,215 |
| -1 | -5 | -43 | -61 | -215 | -305 | -941 | -2,623 | -4,705 | -13,115 | -40,463 | -57,401 | -202,315 | -287,005 | -2,468,243 | -12,341,215 |
