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 237,263,257, 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 | 237,263,257 | |
| -1 | -237,263,257 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 237,263,257.
Example:
1 x 237,263,257 = 237,263,257
and
-1 x -237,263,257 = 237,263,257
Notice both answers equal 237,263,257
With that explanation out of the way, let's continue. Next, we take the number 237,263,257 and divide it by 2:
237,263,257 ÷ 2 = 118,631,628.5
If the quotient is a whole number, then 2 and 118,631,628.5 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 | 237,263,257 | |
| -1 | -237,263,257 |
Now, we try dividing 237,263,257 by 3:
237,263,257 ÷ 3 = 79,087,752.3333
If the quotient is a whole number, then 3 and 79,087,752.3333 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 | 237,263,257 | |
| -1 | -237,263,257 |
Let's try dividing by 4:
237,263,257 ÷ 4 = 59,315,814.25
If the quotient is a whole number, then 4 and 59,315,814.25 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 | 237,263,257 | |
| -1 | 237,263,257 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 439 | 3,073 | 4,829 | 7,019 | 33,803 | 49,133 | 77,209 | 540,463 | 3,081,341 | 21,569,387 | 33,894,751 | 237,263,257 |
| -1 | -7 | -11 | -77 | -439 | -3,073 | -4,829 | -7,019 | -33,803 | -49,133 | -77,209 | -540,463 | -3,081,341 | -21,569,387 | -33,894,751 | -237,263,257 |
