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 12,423,611, 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 | 12,423,611 | |
-1 | -12,423,611 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,423,611.
Example:
1 x 12,423,611 = 12,423,611
and
-1 x -12,423,611 = 12,423,611
Notice both answers equal 12,423,611
With that explanation out of the way, let's continue. Next, we take the number 12,423,611 and divide it by 2:
12,423,611 ÷ 2 = 6,211,805.5
If the quotient is a whole number, then 2 and 6,211,805.5 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 | 12,423,611 | |
-1 | -12,423,611 |
Now, we try dividing 12,423,611 by 3:
12,423,611 ÷ 3 = 4,141,203.6667
If the quotient is a whole number, then 3 and 4,141,203.6667 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 | 12,423,611 | |
-1 | -12,423,611 |
Let's try dividing by 4:
12,423,611 ÷ 4 = 3,105,902.75
If the quotient is a whole number, then 4 and 3,105,902.75 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 | 12,423,611 | |
-1 | 12,423,611 |
If you did it right, you will end up with this table:
1 | 23 | 540,157 | 12,423,611 |
-1 | -23 | -540,157 | -12,423,611 |
