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 522,263,147, 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 | 522,263,147 | |
| -1 | -522,263,147 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 522,263,147.
Example:
1 x 522,263,147 = 522,263,147
and
-1 x -522,263,147 = 522,263,147
Notice both answers equal 522,263,147
With that explanation out of the way, let's continue. Next, we take the number 522,263,147 and divide it by 2:
522,263,147 ÷ 2 = 261,131,573.5
If the quotient is a whole number, then 2 and 261,131,573.5 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 | 522,263,147 | |
| -1 | -522,263,147 |
Now, we try dividing 522,263,147 by 3:
522,263,147 ÷ 3 = 174,087,715.6667
If the quotient is a whole number, then 3 and 174,087,715.6667 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 | 522,263,147 | |
| -1 | -522,263,147 |
Let's try dividing by 4:
522,263,147 ÷ 4 = 130,565,786.75
If the quotient is a whole number, then 4 and 130,565,786.75 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 | 522,263,147 | |
| -1 | 522,263,147 |
If you did it right, you will end up with this table:
| 1 | 7 | 241 | 353 | 877 | 1,687 | 2,471 | 6,139 | 85,073 | 211,357 | 309,581 | 595,511 | 1,479,499 | 2,167,067 | 74,609,021 | 522,263,147 |
| -1 | -7 | -241 | -353 | -877 | -1,687 | -2,471 | -6,139 | -85,073 | -211,357 | -309,581 | -595,511 | -1,479,499 | -2,167,067 | -74,609,021 | -522,263,147 |
