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 1,200,119, 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 | 1,200,119 | |
-1 | -1,200,119 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 1,200,119.
Example:
1 x 1,200,119 = 1,200,119
and
-1 x -1,200,119 = 1,200,119
Notice both answers equal 1,200,119
With that explanation out of the way, let's continue. Next, we take the number 1,200,119 and divide it by 2:
1,200,119 ÷ 2 = 600,059.5
If the quotient is a whole number, then 2 and 600,059.5 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 | 1,200,119 | |
-1 | -1,200,119 |
Now, we try dividing 1,200,119 by 3:
1,200,119 ÷ 3 = 400,039.6667
If the quotient is a whole number, then 3 and 400,039.6667 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 | 1,200,119 | |
-1 | -1,200,119 |
Let's try dividing by 4:
1,200,119 ÷ 4 = 300,029.75
If the quotient is a whole number, then 4 and 300,029.75 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 | 1,200,119 | |
-1 | 1,200,119 |
If you did it right, you will end up with this table:
1 | 59 | 20,341 | 1,200,119 |
-1 | -59 | -20,341 | -1,200,119 |
