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 181,475, 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 | 181,475 | |
| -1 | -181,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 181,475.
Example:
1 x 181,475 = 181,475
and
-1 x -181,475 = 181,475
Notice both answers equal 181,475
With that explanation out of the way, let's continue. Next, we take the number 181,475 and divide it by 2:
181,475 ÷ 2 = 90,737.5
If the quotient is a whole number, then 2 and 90,737.5 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 | 181,475 | |
| -1 | -181,475 |
Now, we try dividing 181,475 by 3:
181,475 ÷ 3 = 60,491.6667
If the quotient is a whole number, then 3 and 60,491.6667 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 | 181,475 | |
| -1 | -181,475 |
Let's try dividing by 4:
181,475 ÷ 4 = 45,368.75
If the quotient is a whole number, then 4 and 45,368.75 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 | 181,475 | |
| -1 | 181,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 17 | 25 | 35 | 61 | 85 | 119 | 175 | 305 | 425 | 427 | 595 | 1,037 | 1,525 | 2,135 | 2,975 | 5,185 | 7,259 | 10,675 | 25,925 | 36,295 | 181,475 |
| -1 | -5 | -7 | -17 | -25 | -35 | -61 | -85 | -119 | -175 | -305 | -425 | -427 | -595 | -1,037 | -1,525 | -2,135 | -2,975 | -5,185 | -7,259 | -10,675 | -25,925 | -36,295 | -181,475 |
