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 12,241,463, 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 | 12,241,463 | |
| -1 | -12,241,463 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,241,463.
Example:
1 x 12,241,463 = 12,241,463
and
-1 x -12,241,463 = 12,241,463
Notice both answers equal 12,241,463
With that explanation out of the way, let's continue. Next, we take the number 12,241,463 and divide it by 2:
12,241,463 ÷ 2 = 6,120,731.5
If the quotient is a whole number, then 2 and 6,120,731.5 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 | 12,241,463 | |
| -1 | -12,241,463 |
Now, we try dividing 12,241,463 by 3:
12,241,463 ÷ 3 = 4,080,487.6667
If the quotient is a whole number, then 3 and 4,080,487.6667 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 | 12,241,463 | |
| -1 | -12,241,463 |
Let's try dividing by 4:
12,241,463 ÷ 4 = 3,060,365.75
If the quotient is a whole number, then 4 and 3,060,365.75 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 | 12,241,463 | |
| -1 | 12,241,463 |
If you did it right, you will end up with this table:
| 1 | 13 | 53 | 109 | 163 | 689 | 1,417 | 2,119 | 5,777 | 8,639 | 17,767 | 75,101 | 112,307 | 230,971 | 941,651 | 12,241,463 |
| -1 | -13 | -53 | -109 | -163 | -689 | -1,417 | -2,119 | -5,777 | -8,639 | -17,767 | -75,101 | -112,307 | -230,971 | -941,651 | -12,241,463 |
