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 405,275, 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 | 405,275 | |
| -1 | -405,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 405,275.
Example:
1 x 405,275 = 405,275
and
-1 x -405,275 = 405,275
Notice both answers equal 405,275
With that explanation out of the way, let's continue. Next, we take the number 405,275 and divide it by 2:
405,275 ÷ 2 = 202,637.5
If the quotient is a whole number, then 2 and 202,637.5 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 | 405,275 | |
| -1 | -405,275 |
Now, we try dividing 405,275 by 3:
405,275 ÷ 3 = 135,091.6667
If the quotient is a whole number, then 3 and 135,091.6667 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 | 405,275 | |
| -1 | -405,275 |
Let's try dividing by 4:
405,275 ÷ 4 = 101,318.75
If the quotient is a whole number, then 4 and 101,318.75 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 | 405,275 | |
| -1 | 405,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 25 | 29 | 43 | 65 | 145 | 215 | 325 | 377 | 559 | 725 | 1,075 | 1,247 | 1,885 | 2,795 | 6,235 | 9,425 | 13,975 | 16,211 | 31,175 | 81,055 | 405,275 |
| -1 | -5 | -13 | -25 | -29 | -43 | -65 | -145 | -215 | -325 | -377 | -559 | -725 | -1,075 | -1,247 | -1,885 | -2,795 | -6,235 | -9,425 | -13,975 | -16,211 | -31,175 | -81,055 | -405,275 |
