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 231,740,525, 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 | 231,740,525 | |
| -1 | -231,740,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,740,525.
Example:
1 x 231,740,525 = 231,740,525
and
-1 x -231,740,525 = 231,740,525
Notice both answers equal 231,740,525
With that explanation out of the way, let's continue. Next, we take the number 231,740,525 and divide it by 2:
231,740,525 ÷ 2 = 115,870,262.5
If the quotient is a whole number, then 2 and 115,870,262.5 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 | 231,740,525 | |
| -1 | -231,740,525 |
Now, we try dividing 231,740,525 by 3:
231,740,525 ÷ 3 = 77,246,841.6667
If the quotient is a whole number, then 3 and 77,246,841.6667 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 | 231,740,525 | |
| -1 | -231,740,525 |
Let's try dividing by 4:
231,740,525 ÷ 4 = 57,935,131.25
If the quotient is a whole number, then 4 and 57,935,131.25 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 | 231,740,525 | |
| -1 | 231,740,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 25 | 61 | 115 | 305 | 575 | 1,403 | 1,525 | 6,607 | 7,015 | 33,035 | 35,075 | 151,961 | 165,175 | 403,027 | 759,805 | 2,015,135 | 3,799,025 | 9,269,621 | 10,075,675 | 46,348,105 | 231,740,525 |
| -1 | -5 | -23 | -25 | -61 | -115 | -305 | -575 | -1,403 | -1,525 | -6,607 | -7,015 | -33,035 | -35,075 | -151,961 | -165,175 | -403,027 | -759,805 | -2,015,135 | -3,799,025 | -9,269,621 | -10,075,675 | -46,348,105 | -231,740,525 |
