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 237,575, 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 | 237,575 | |
| -1 | -237,575 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 237,575.
Example:
1 x 237,575 = 237,575
and
-1 x -237,575 = 237,575
Notice both answers equal 237,575
With that explanation out of the way, let's continue. Next, we take the number 237,575 and divide it by 2:
237,575 ÷ 2 = 118,787.5
If the quotient is a whole number, then 2 and 118,787.5 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 | 237,575 | |
| -1 | -237,575 |
Now, we try dividing 237,575 by 3:
237,575 ÷ 3 = 79,191.6667
If the quotient is a whole number, then 3 and 79,191.6667 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 | 237,575 | |
| -1 | -237,575 |
Let's try dividing by 4:
237,575 ÷ 4 = 59,393.75
If the quotient is a whole number, then 4 and 59,393.75 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 | 237,575 | |
| -1 | 237,575 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 17 | 25 | 43 | 65 | 85 | 215 | 221 | 325 | 425 | 559 | 731 | 1,075 | 1,105 | 2,795 | 3,655 | 5,525 | 9,503 | 13,975 | 18,275 | 47,515 | 237,575 |
| -1 | -5 | -13 | -17 | -25 | -43 | -65 | -85 | -215 | -221 | -325 | -425 | -559 | -731 | -1,075 | -1,105 | -2,795 | -3,655 | -5,525 | -9,503 | -13,975 | -18,275 | -47,515 | -237,575 |
