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 237,246,185, 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 | 237,246,185 | |
| -1 | -237,246,185 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 237,246,185.
Example:
1 x 237,246,185 = 237,246,185
and
-1 x -237,246,185 = 237,246,185
Notice both answers equal 237,246,185
With that explanation out of the way, let's continue. Next, we take the number 237,246,185 and divide it by 2:
237,246,185 ÷ 2 = 118,623,092.5
If the quotient is a whole number, then 2 and 118,623,092.5 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 | 237,246,185 | |
| -1 | -237,246,185 |
Now, we try dividing 237,246,185 by 3:
237,246,185 ÷ 3 = 79,082,061.6667
If the quotient is a whole number, then 3 and 79,082,061.6667 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 | 237,246,185 | |
| -1 | -237,246,185 |
Let's try dividing by 4:
237,246,185 ÷ 4 = 59,311,546.25
If the quotient is a whole number, then 4 and 59,311,546.25 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 | 237,246,185 | |
| -1 | 237,246,185 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 1,163 | 3,709 | 5,815 | 12,793 | 18,545 | 40,799 | 63,965 | 203,995 | 4,313,567 | 21,567,835 | 47,449,237 | 237,246,185 |
| -1 | -5 | -11 | -55 | -1,163 | -3,709 | -5,815 | -12,793 | -18,545 | -40,799 | -63,965 | -203,995 | -4,313,567 | -21,567,835 | -47,449,237 | -237,246,185 |
