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 80,335,211, 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 | 80,335,211 | |
| -1 | -80,335,211 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 80,335,211.
Example:
1 x 80,335,211 = 80,335,211
and
-1 x -80,335,211 = 80,335,211
Notice both answers equal 80,335,211
With that explanation out of the way, let's continue. Next, we take the number 80,335,211 and divide it by 2:
80,335,211 ÷ 2 = 40,167,605.5
If the quotient is a whole number, then 2 and 40,167,605.5 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 | 80,335,211 | |
| -1 | -80,335,211 |
Now, we try dividing 80,335,211 by 3:
80,335,211 ÷ 3 = 26,778,403.6667
If the quotient is a whole number, then 3 and 26,778,403.6667 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 | 80,335,211 | |
| -1 | -80,335,211 |
Let's try dividing by 4:
80,335,211 ÷ 4 = 20,083,802.75
If the quotient is a whole number, then 4 and 20,083,802.75 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 | 80,335,211 | |
| -1 | 80,335,211 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 67 | 209 | 737 | 1,273 | 5,737 | 14,003 | 63,107 | 109,003 | 384,379 | 1,199,033 | 4,228,169 | 7,303,201 | 80,335,211 |
| -1 | -11 | -19 | -67 | -209 | -737 | -1,273 | -5,737 | -14,003 | -63,107 | -109,003 | -384,379 | -1,199,033 | -4,228,169 | -7,303,201 | -80,335,211 |
