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 237,433,805, 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 | 237,433,805 | |
| -1 | -237,433,805 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 237,433,805.
Example:
1 x 237,433,805 = 237,433,805
and
-1 x -237,433,805 = 237,433,805
Notice both answers equal 237,433,805
With that explanation out of the way, let's continue. Next, we take the number 237,433,805 and divide it by 2:
237,433,805 ÷ 2 = 118,716,902.5
If the quotient is a whole number, then 2 and 118,716,902.5 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 | 237,433,805 | |
| -1 | -237,433,805 |
Now, we try dividing 237,433,805 by 3:
237,433,805 ÷ 3 = 79,144,601.6667
If the quotient is a whole number, then 3 and 79,144,601.6667 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 | 237,433,805 | |
| -1 | -237,433,805 |
Let's try dividing by 4:
237,433,805 ÷ 4 = 59,358,451.25
If the quotient is a whole number, then 4 and 59,358,451.25 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 | 237,433,805 | |
| -1 | 237,433,805 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 31 | 35 | 155 | 217 | 1,085 | 218,833 | 1,094,165 | 1,531,831 | 6,783,823 | 7,659,155 | 33,919,115 | 47,486,761 | 237,433,805 |
| -1 | -5 | -7 | -31 | -35 | -155 | -217 | -1,085 | -218,833 | -1,094,165 | -1,531,831 | -6,783,823 | -7,659,155 | -33,919,115 | -47,486,761 | -237,433,805 |
