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 82,562,515, 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 | 82,562,515 | |
| -1 | -82,562,515 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 82,562,515.
Example:
1 x 82,562,515 = 82,562,515
and
-1 x -82,562,515 = 82,562,515
Notice both answers equal 82,562,515
With that explanation out of the way, let's continue. Next, we take the number 82,562,515 and divide it by 2:
82,562,515 ÷ 2 = 41,281,257.5
If the quotient is a whole number, then 2 and 41,281,257.5 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 | 82,562,515 | |
| -1 | -82,562,515 |
Now, we try dividing 82,562,515 by 3:
82,562,515 ÷ 3 = 27,520,838.3333
If the quotient is a whole number, then 3 and 27,520,838.3333 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 | 82,562,515 | |
| -1 | -82,562,515 |
Let's try dividing by 4:
82,562,515 ÷ 4 = 20,640,628.75
If the quotient is a whole number, then 4 and 20,640,628.75 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 | 82,562,515 | |
| -1 | 82,562,515 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 229 | 1,145 | 1,603 | 8,015 | 10,301 | 51,505 | 72,107 | 360,535 | 2,358,929 | 11,794,645 | 16,512,503 | 82,562,515 |
| -1 | -5 | -7 | -35 | -229 | -1,145 | -1,603 | -8,015 | -10,301 | -51,505 | -72,107 | -360,535 | -2,358,929 | -11,794,645 | -16,512,503 | -82,562,515 |
