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 403,975, 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 | 403,975 | |
| -1 | -403,975 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 403,975.
Example:
1 x 403,975 = 403,975
and
-1 x -403,975 = 403,975
Notice both answers equal 403,975
With that explanation out of the way, let's continue. Next, we take the number 403,975 and divide it by 2:
403,975 ÷ 2 = 201,987.5
If the quotient is a whole number, then 2 and 201,987.5 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 | 403,975 | |
| -1 | -403,975 |
Now, we try dividing 403,975 by 3:
403,975 ÷ 3 = 134,658.3333
If the quotient is a whole number, then 3 and 134,658.3333 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 | 403,975 | |
| -1 | -403,975 |
Let's try dividing by 4:
403,975 ÷ 4 = 100,993.75
If the quotient is a whole number, then 4 and 100,993.75 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 | 403,975 | |
| -1 | 403,975 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 13 | 25 | 55 | 65 | 113 | 143 | 275 | 325 | 565 | 715 | 1,243 | 1,469 | 2,825 | 3,575 | 6,215 | 7,345 | 16,159 | 31,075 | 36,725 | 80,795 | 403,975 |
| -1 | -5 | -11 | -13 | -25 | -55 | -65 | -113 | -143 | -275 | -325 | -565 | -715 | -1,243 | -1,469 | -2,825 | -3,575 | -6,215 | -7,345 | -16,159 | -31,075 | -36,725 | -80,795 | -403,975 |
