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 527,447,615, 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 | 527,447,615 | |
| -1 | -527,447,615 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 527,447,615.
Example:
1 x 527,447,615 = 527,447,615
and
-1 x -527,447,615 = 527,447,615
Notice both answers equal 527,447,615
With that explanation out of the way, let's continue. Next, we take the number 527,447,615 and divide it by 2:
527,447,615 ÷ 2 = 263,723,807.5
If the quotient is a whole number, then 2 and 263,723,807.5 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 | 527,447,615 | |
| -1 | -527,447,615 |
Now, we try dividing 527,447,615 by 3:
527,447,615 ÷ 3 = 175,815,871.6667
If the quotient is a whole number, then 3 and 175,815,871.6667 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 | 527,447,615 | |
| -1 | -527,447,615 |
Let's try dividing by 4:
527,447,615 ÷ 4 = 131,861,903.75
If the quotient is a whole number, then 4 and 131,861,903.75 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 | 527,447,615 | |
| -1 | 527,447,615 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 719 | 3,595 | 6,379 | 16,537 | 31,895 | 82,685 | 146,717 | 733,585 | 4,586,501 | 22,932,505 | 105,489,523 | 527,447,615 |
| -1 | -5 | -23 | -115 | -719 | -3,595 | -6,379 | -16,537 | -31,895 | -82,685 | -146,717 | -733,585 | -4,586,501 | -22,932,505 | -105,489,523 | -527,447,615 |
