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 321,475, 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 | 321,475 | |
| -1 | -321,475 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 321,475.
Example:
1 x 321,475 = 321,475
and
-1 x -321,475 = 321,475
Notice both answers equal 321,475
With that explanation out of the way, let's continue. Next, we take the number 321,475 and divide it by 2:
321,475 ÷ 2 = 160,737.5
If the quotient is a whole number, then 2 and 160,737.5 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 | 321,475 | |
| -1 | -321,475 |
Now, we try dividing 321,475 by 3:
321,475 ÷ 3 = 107,158.3333
If the quotient is a whole number, then 3 and 107,158.3333 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 | 321,475 | |
| -1 | -321,475 |
Let's try dividing by 4:
321,475 ÷ 4 = 80,368.75
If the quotient is a whole number, then 4 and 80,368.75 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 | 321,475 | |
| -1 | 321,475 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 11 | 25 | 35 | 55 | 77 | 167 | 175 | 275 | 385 | 835 | 1,169 | 1,837 | 1,925 | 4,175 | 5,845 | 9,185 | 12,859 | 29,225 | 45,925 | 64,295 | 321,475 |
| -1 | -5 | -7 | -11 | -25 | -35 | -55 | -77 | -167 | -175 | -275 | -385 | -835 | -1,169 | -1,837 | -1,925 | -4,175 | -5,845 | -9,185 | -12,859 | -29,225 | -45,925 | -64,295 | -321,475 |
