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 83,242,805, 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 | 83,242,805 | |
| -1 | -83,242,805 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 83,242,805.
Example:
1 x 83,242,805 = 83,242,805
and
-1 x -83,242,805 = 83,242,805
Notice both answers equal 83,242,805
With that explanation out of the way, let's continue. Next, we take the number 83,242,805 and divide it by 2:
83,242,805 ÷ 2 = 41,621,402.5
If the quotient is a whole number, then 2 and 41,621,402.5 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 | 83,242,805 | |
| -1 | -83,242,805 |
Now, we try dividing 83,242,805 by 3:
83,242,805 ÷ 3 = 27,747,601.6667
If the quotient is a whole number, then 3 and 27,747,601.6667 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 | 83,242,805 | |
| -1 | -83,242,805 |
Let's try dividing by 4:
83,242,805 ÷ 4 = 20,810,701.25
If the quotient is a whole number, then 4 and 20,810,701.25 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 | 83,242,805 | |
| -1 | 83,242,805 |
If you did it right, you will end up with this table:
| 1 | 5 | 59 | 181 | 295 | 905 | 1,559 | 7,795 | 10,679 | 53,395 | 91,981 | 282,179 | 459,905 | 1,410,895 | 16,648,561 | 83,242,805 |
| -1 | -5 | -59 | -181 | -295 | -905 | -1,559 | -7,795 | -10,679 | -53,395 | -91,981 | -282,179 | -459,905 | -1,410,895 | -16,648,561 | -83,242,805 |
