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 527,341,805, 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 | 527,341,805 | |
| -1 | -527,341,805 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 527,341,805.
Example:
1 x 527,341,805 = 527,341,805
and
-1 x -527,341,805 = 527,341,805
Notice both answers equal 527,341,805
With that explanation out of the way, let's continue. Next, we take the number 527,341,805 and divide it by 2:
527,341,805 ÷ 2 = 263,670,902.5
If the quotient is a whole number, then 2 and 263,670,902.5 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 | 527,341,805 | |
| -1 | -527,341,805 |
Now, we try dividing 527,341,805 by 3:
527,341,805 ÷ 3 = 175,780,601.6667
If the quotient is a whole number, then 3 and 175,780,601.6667 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 | 527,341,805 | |
| -1 | -527,341,805 |
Let's try dividing by 4:
527,341,805 ÷ 4 = 131,835,451.25
If the quotient is a whole number, then 4 and 131,835,451.25 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 | 527,341,805 | |
| -1 | 527,341,805 |
If you did it right, you will end up with this table:
| 1 | 5 | 157 | 373 | 785 | 1,801 | 1,865 | 9,005 | 58,561 | 282,757 | 292,805 | 671,773 | 1,413,785 | 3,358,865 | 105,468,361 | 527,341,805 |
| -1 | -5 | -157 | -373 | -785 | -1,801 | -1,865 | -9,005 | -58,561 | -282,757 | -292,805 | -671,773 | -1,413,785 | -3,358,865 | -105,468,361 | -527,341,805 |
