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 238,525, 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 | 238,525 | |
| -1 | -238,525 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 238,525.
Example:
1 x 238,525 = 238,525
and
-1 x -238,525 = 238,525
Notice both answers equal 238,525
With that explanation out of the way, let's continue. Next, we take the number 238,525 and divide it by 2:
238,525 ÷ 2 = 119,262.5
If the quotient is a whole number, then 2 and 119,262.5 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 | 238,525 | |
| -1 | -238,525 |
Now, we try dividing 238,525 by 3:
238,525 ÷ 3 = 79,508.3333
If the quotient is a whole number, then 3 and 79,508.3333 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 | 238,525 | |
| -1 | -238,525 |
Let's try dividing by 4:
238,525 ÷ 4 = 59,631.25
If the quotient is a whole number, then 4 and 59,631.25 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 | 238,525 | |
| -1 | 238,525 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 29 | 35 | 47 | 145 | 175 | 203 | 235 | 329 | 725 | 1,015 | 1,175 | 1,363 | 1,645 | 5,075 | 6,815 | 8,225 | 9,541 | 34,075 | 47,705 | 238,525 |
| -1 | -5 | -7 | -25 | -29 | -35 | -47 | -145 | -175 | -203 | -235 | -329 | -725 | -1,015 | -1,175 | -1,363 | -1,645 | -5,075 | -6,815 | -8,225 | -9,541 | -34,075 | -47,705 | -238,525 |
