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 237,446,755, 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 | 237,446,755 | |
| -1 | -237,446,755 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 237,446,755.
Example:
1 x 237,446,755 = 237,446,755
and
-1 x -237,446,755 = 237,446,755
Notice both answers equal 237,446,755
With that explanation out of the way, let's continue. Next, we take the number 237,446,755 and divide it by 2:
237,446,755 ÷ 2 = 118,723,377.5
If the quotient is a whole number, then 2 and 118,723,377.5 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 | 237,446,755 | |
| -1 | -237,446,755 |
Now, we try dividing 237,446,755 by 3:
237,446,755 ÷ 3 = 79,148,918.3333
If the quotient is a whole number, then 3 and 79,148,918.3333 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 | 237,446,755 | |
| -1 | -237,446,755 |
Let's try dividing by 4:
237,446,755 ÷ 4 = 59,361,688.75
If the quotient is a whole number, then 4 and 59,361,688.75 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 | 237,446,755 | |
| -1 | 237,446,755 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 13 | 35 | 65 | 91 | 455 | 521,861 | 2,609,305 | 3,653,027 | 6,784,193 | 18,265,135 | 33,920,965 | 47,489,351 | 237,446,755 |
| -1 | -5 | -7 | -13 | -35 | -65 | -91 | -455 | -521,861 | -2,609,305 | -3,653,027 | -6,784,193 | -18,265,135 | -33,920,965 | -47,489,351 | -237,446,755 |
