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 537,215,375, 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 | 537,215,375 | |
| -1 | -537,215,375 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 537,215,375.
Example:
1 x 537,215,375 = 537,215,375
and
-1 x -537,215,375 = 537,215,375
Notice both answers equal 537,215,375
With that explanation out of the way, let's continue. Next, we take the number 537,215,375 and divide it by 2:
537,215,375 ÷ 2 = 268,607,687.5
If the quotient is a whole number, then 2 and 268,607,687.5 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 | 537,215,375 | |
| -1 | -537,215,375 |
Now, we try dividing 537,215,375 by 3:
537,215,375 ÷ 3 = 179,071,791.6667
If the quotient is a whole number, then 3 and 179,071,791.6667 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 | 537,215,375 | |
| -1 | -537,215,375 |
Let's try dividing by 4:
537,215,375 ÷ 4 = 134,303,843.75
If the quotient is a whole number, then 4 and 134,303,843.75 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 | 537,215,375 | |
| -1 | 537,215,375 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 491 | 2,455 | 8,753 | 12,275 | 43,765 | 61,375 | 218,825 | 1,094,125 | 4,297,723 | 21,488,615 | 107,443,075 | 537,215,375 |
| -1 | -5 | -25 | -125 | -491 | -2,455 | -8,753 | -12,275 | -43,765 | -61,375 | -218,825 | -1,094,125 | -4,297,723 | -21,488,615 | -107,443,075 | -537,215,375 |
