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 12,111,401, 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 | 12,111,401 | |
-1 | -12,111,401 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,111,401.
Example:
1 x 12,111,401 = 12,111,401
and
-1 x -12,111,401 = 12,111,401
Notice both answers equal 12,111,401
With that explanation out of the way, let's continue. Next, we take the number 12,111,401 and divide it by 2:
12,111,401 ÷ 2 = 6,055,700.5
If the quotient is a whole number, then 2 and 6,055,700.5 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 | 12,111,401 | |
-1 | -12,111,401 |
Now, we try dividing 12,111,401 by 3:
12,111,401 ÷ 3 = 4,037,133.6667
If the quotient is a whole number, then 3 and 4,037,133.6667 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 | 12,111,401 | |
-1 | -12,111,401 |
Let's try dividing by 4:
12,111,401 ÷ 4 = 3,027,850.25
If the quotient is a whole number, then 4 and 3,027,850.25 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 | 12,111,401 | |
-1 | 12,111,401 |
If you did it right, you will end up with this table:
1 | 53 | 228,517 | 12,111,401 |
-1 | -53 | -228,517 | -12,111,401 |
