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 237,418,357, 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 | 237,418,357 | |
| -1 | -237,418,357 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 237,418,357.
Example:
1 x 237,418,357 = 237,418,357
and
-1 x -237,418,357 = 237,418,357
Notice both answers equal 237,418,357
With that explanation out of the way, let's continue. Next, we take the number 237,418,357 and divide it by 2:
237,418,357 ÷ 2 = 118,709,178.5
If the quotient is a whole number, then 2 and 118,709,178.5 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 | 237,418,357 | |
| -1 | -237,418,357 |
Now, we try dividing 237,418,357 by 3:
237,418,357 ÷ 3 = 79,139,452.3333
If the quotient is a whole number, then 3 and 79,139,452.3333 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 | 237,418,357 | |
| -1 | -237,418,357 |
Let's try dividing by 4:
237,418,357 ÷ 4 = 59,354,589.25
If the quotient is a whole number, then 4 and 59,354,589.25 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 | 237,418,357 | |
| -1 | 237,418,357 |
If you did it right, you will end up with this table:
| 1 | 11 | 19 | 151 | 209 | 1,661 | 2,869 | 7,523 | 31,559 | 82,753 | 142,937 | 1,135,973 | 1,572,307 | 12,495,703 | 21,583,487 | 237,418,357 |
| -1 | -11 | -19 | -151 | -209 | -1,661 | -2,869 | -7,523 | -31,559 | -82,753 | -142,937 | -1,135,973 | -1,572,307 | -12,495,703 | -21,583,487 | -237,418,357 |
