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 526,636,115, 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 | 526,636,115 | |
| -1 | -526,636,115 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 526,636,115.
Example:
1 x 526,636,115 = 526,636,115
and
-1 x -526,636,115 = 526,636,115
Notice both answers equal 526,636,115
With that explanation out of the way, let's continue. Next, we take the number 526,636,115 and divide it by 2:
526,636,115 ÷ 2 = 263,318,057.5
If the quotient is a whole number, then 2 and 263,318,057.5 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 | 526,636,115 | |
| -1 | -526,636,115 |
Now, we try dividing 526,636,115 by 3:
526,636,115 ÷ 3 = 175,545,371.6667
If the quotient is a whole number, then 3 and 175,545,371.6667 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 | 526,636,115 | |
| -1 | -526,636,115 |
Let's try dividing by 4:
526,636,115 ÷ 4 = 131,659,028.75
If the quotient is a whole number, then 4 and 131,659,028.75 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 | 526,636,115 | |
| -1 | 526,636,115 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 85 | 283 | 1,415 | 4,811 | 21,893 | 24,055 | 109,465 | 372,181 | 1,860,905 | 6,195,719 | 30,978,595 | 105,327,223 | 526,636,115 |
| -1 | -5 | -17 | -85 | -283 | -1,415 | -4,811 | -21,893 | -24,055 | -109,465 | -372,181 | -1,860,905 | -6,195,719 | -30,978,595 | -105,327,223 | -526,636,115 |
