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 120,433, 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 | 120,433 | |
-1 | -120,433 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 120,433.
Example:
1 x 120,433 = 120,433
and
-1 x -120,433 = 120,433
Notice both answers equal 120,433
With that explanation out of the way, let's continue. Next, we take the number 120,433 and divide it by 2:
120,433 ÷ 2 = 60,216.5
If the quotient is a whole number, then 2 and 60,216.5 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 | 120,433 | |
-1 | -120,433 |
Now, we try dividing 120,433 by 3:
120,433 ÷ 3 = 40,144.3333
If the quotient is a whole number, then 3 and 40,144.3333 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 | 120,433 | |
-1 | -120,433 |
Let's try dividing by 4:
120,433 ÷ 4 = 30,108.25
If the quotient is a whole number, then 4 and 30,108.25 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 | 120,433 | |
-1 | 120,433 |
If you did it right, you will end up with this table:
1 | 83 | 1,451 | 120,433 |
-1 | -83 | -1,451 | -120,433 |
