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 80,103,337, 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 | 80,103,337 | |
| -1 | -80,103,337 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 80,103,337.
Example:
1 x 80,103,337 = 80,103,337
and
-1 x -80,103,337 = 80,103,337
Notice both answers equal 80,103,337
With that explanation out of the way, let's continue. Next, we take the number 80,103,337 and divide it by 2:
80,103,337 ÷ 2 = 40,051,668.5
If the quotient is a whole number, then 2 and 40,051,668.5 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 | 80,103,337 | |
| -1 | -80,103,337 |
Now, we try dividing 80,103,337 by 3:
80,103,337 ÷ 3 = 26,701,112.3333
If the quotient is a whole number, then 3 and 26,701,112.3333 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 | 80,103,337 | |
| -1 | -80,103,337 |
Let's try dividing by 4:
80,103,337 ÷ 4 = 20,025,834.25
If the quotient is a whole number, then 4 and 20,025,834.25 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 | 80,103,337 | |
| -1 | 80,103,337 |
If you did it right, you will end up with this table:
| 1 | 17 | 109 | 139 | 311 | 1,853 | 2,363 | 5,287 | 15,151 | 33,899 | 43,229 | 257,567 | 576,283 | 734,893 | 4,711,961 | 80,103,337 |
| -1 | -17 | -109 | -139 | -311 | -1,853 | -2,363 | -5,287 | -15,151 | -33,899 | -43,229 | -257,567 | -576,283 | -734,893 | -4,711,961 | -80,103,337 |
