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 231,751,555, 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 | 231,751,555 | |
| -1 | -231,751,555 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 231,751,555.
Example:
1 x 231,751,555 = 231,751,555
and
-1 x -231,751,555 = 231,751,555
Notice both answers equal 231,751,555
With that explanation out of the way, let's continue. Next, we take the number 231,751,555 and divide it by 2:
231,751,555 ÷ 2 = 115,875,777.5
If the quotient is a whole number, then 2 and 115,875,777.5 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 | 231,751,555 | |
| -1 | -231,751,555 |
Now, we try dividing 231,751,555 by 3:
231,751,555 ÷ 3 = 77,250,518.3333
If the quotient is a whole number, then 3 and 77,250,518.3333 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 | 231,751,555 | |
| -1 | -231,751,555 |
Let's try dividing by 4:
231,751,555 ÷ 4 = 57,937,888.75
If the quotient is a whole number, then 4 and 57,937,888.75 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 | 231,751,555 | |
| -1 | 231,751,555 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 457 | 2,285 | 3,199 | 14,489 | 15,995 | 72,445 | 101,423 | 507,115 | 6,621,473 | 33,107,365 | 46,350,311 | 231,751,555 |
| -1 | -5 | -7 | -35 | -457 | -2,285 | -3,199 | -14,489 | -15,995 | -72,445 | -101,423 | -507,115 | -6,621,473 | -33,107,365 | -46,350,311 | -231,751,555 |
