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 231,062,575, 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 | 231,062,575 | |
| -1 | -231,062,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,062,575.
Example:
1 x 231,062,575 = 231,062,575
and
-1 x -231,062,575 = 231,062,575
Notice both answers equal 231,062,575
With that explanation out of the way, let's continue. Next, we take the number 231,062,575 and divide it by 2:
231,062,575 ÷ 2 = 115,531,287.5
If the quotient is a whole number, then 2 and 115,531,287.5 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 | 231,062,575 | |
| -1 | -231,062,575 |
Now, we try dividing 231,062,575 by 3:
231,062,575 ÷ 3 = 77,020,858.3333
If the quotient is a whole number, then 3 and 77,020,858.3333 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 | 231,062,575 | |
| -1 | -231,062,575 |
Let's try dividing by 4:
231,062,575 ÷ 4 = 57,765,643.75
If the quotient is a whole number, then 4 and 57,765,643.75 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 | 231,062,575 | |
| -1 | 231,062,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 29 | 47 | 145 | 235 | 725 | 1,175 | 1,363 | 6,781 | 6,815 | 33,905 | 34,075 | 169,525 | 196,649 | 318,707 | 983,245 | 1,593,535 | 4,916,225 | 7,967,675 | 9,242,503 | 46,212,515 | 231,062,575 |
| -1 | -5 | -25 | -29 | -47 | -145 | -235 | -725 | -1,175 | -1,363 | -6,781 | -6,815 | -33,905 | -34,075 | -169,525 | -196,649 | -318,707 | -983,245 | -1,593,535 | -4,916,225 | -7,967,675 | -9,242,503 | -46,212,515 | -231,062,575 |
