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 82,803,197, 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 | 82,803,197 | |
| -1 | -82,803,197 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 82,803,197.
Example:
1 x 82,803,197 = 82,803,197
and
-1 x -82,803,197 = 82,803,197
Notice both answers equal 82,803,197
With that explanation out of the way, let's continue. Next, we take the number 82,803,197 and divide it by 2:
82,803,197 ÷ 2 = 41,401,598.5
If the quotient is a whole number, then 2 and 41,401,598.5 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 | 82,803,197 | |
| -1 | -82,803,197 |
Now, we try dividing 82,803,197 by 3:
82,803,197 ÷ 3 = 27,601,065.6667
If the quotient is a whole number, then 3 and 27,601,065.6667 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 | 82,803,197 | |
| -1 | -82,803,197 |
Let's try dividing by 4:
82,803,197 ÷ 4 = 20,700,799.25
If the quotient is a whole number, then 4 and 20,700,799.25 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 | 82,803,197 | |
| -1 | 82,803,197 |
If you did it right, you will end up with this table:
| 1 | 19 | 23 | 89 | 437 | 1,691 | 2,047 | 2,129 | 38,893 | 40,451 | 48,967 | 189,481 | 930,373 | 3,600,139 | 4,358,063 | 82,803,197 |
| -1 | -19 | -23 | -89 | -437 | -1,691 | -2,047 | -2,129 | -38,893 | -40,451 | -48,967 | -189,481 | -930,373 | -3,600,139 | -4,358,063 | -82,803,197 |
