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 80,366,875, 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 | 80,366,875 | |
| -1 | -80,366,875 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 80,366,875.
Example:
1 x 80,366,875 = 80,366,875
and
-1 x -80,366,875 = 80,366,875
Notice both answers equal 80,366,875
With that explanation out of the way, let's continue. Next, we take the number 80,366,875 and divide it by 2:
80,366,875 ÷ 2 = 40,183,437.5
If the quotient is a whole number, then 2 and 40,183,437.5 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 | 80,366,875 | |
| -1 | -80,366,875 |
Now, we try dividing 80,366,875 by 3:
80,366,875 ÷ 3 = 26,788,958.3333
If the quotient is a whole number, then 3 and 26,788,958.3333 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 | 80,366,875 | |
| -1 | -80,366,875 |
Let's try dividing by 4:
80,366,875 ÷ 4 = 20,091,718.75
If the quotient is a whole number, then 4 and 20,091,718.75 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 | 80,366,875 | |
| -1 | 80,366,875 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 149 | 625 | 745 | 863 | 3,725 | 4,315 | 18,625 | 21,575 | 93,125 | 107,875 | 128,587 | 539,375 | 642,935 | 3,214,675 | 16,073,375 | 80,366,875 |
| -1 | -5 | -25 | -125 | -149 | -625 | -745 | -863 | -3,725 | -4,315 | -18,625 | -21,575 | -93,125 | -107,875 | -128,587 | -539,375 | -642,935 | -3,214,675 | -16,073,375 | -80,366,875 |
