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 12,078,037, 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 | 12,078,037 | |
-1 | -12,078,037 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 12,078,037.
Example:
1 x 12,078,037 = 12,078,037
and
-1 x -12,078,037 = 12,078,037
Notice both answers equal 12,078,037
With that explanation out of the way, let's continue. Next, we take the number 12,078,037 and divide it by 2:
12,078,037 ÷ 2 = 6,039,018.5
If the quotient is a whole number, then 2 and 6,039,018.5 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 | 12,078,037 | |
-1 | -12,078,037 |
Now, we try dividing 12,078,037 by 3:
12,078,037 ÷ 3 = 4,026,012.3333
If the quotient is a whole number, then 3 and 4,026,012.3333 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 | 12,078,037 | |
-1 | -12,078,037 |
Let's try dividing by 4:
12,078,037 ÷ 4 = 3,019,509.25
If the quotient is a whole number, then 4 and 3,019,509.25 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 | 12,078,037 | |
-1 | 12,078,037 |
If you did it right, you will end up with this table:
1 | 151 | 79,987 | 12,078,037 |
-1 | -151 | -79,987 | -12,078,037 |
