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 237,435,005, 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 | 237,435,005 | |
| -1 | -237,435,005 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 237,435,005.
Example:
1 x 237,435,005 = 237,435,005
and
-1 x -237,435,005 = 237,435,005
Notice both answers equal 237,435,005
With that explanation out of the way, let's continue. Next, we take the number 237,435,005 and divide it by 2:
237,435,005 ÷ 2 = 118,717,502.5
If the quotient is a whole number, then 2 and 118,717,502.5 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 | 237,435,005 | |
| -1 | -237,435,005 |
Now, we try dividing 237,435,005 by 3:
237,435,005 ÷ 3 = 79,145,001.6667
If the quotient is a whole number, then 3 and 79,145,001.6667 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 | 237,435,005 | |
| -1 | -237,435,005 |
Let's try dividing by 4:
237,435,005 ÷ 4 = 59,358,751.25
If the quotient is a whole number, then 4 and 59,358,751.25 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 | 237,435,005 | |
| -1 | 237,435,005 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 71 | 85 | 355 | 1,207 | 6,035 | 39,343 | 196,715 | 668,831 | 2,793,353 | 3,344,155 | 13,966,765 | 47,487,001 | 237,435,005 |
| -1 | -5 | -17 | -71 | -85 | -355 | -1,207 | -6,035 | -39,343 | -196,715 | -668,831 | -2,793,353 | -3,344,155 | -13,966,765 | -47,487,001 | -237,435,005 |
