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 389,795, 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 | 389,795 | |
| -1 | -389,795 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 389,795.
Example:
1 x 389,795 = 389,795
and
-1 x -389,795 = 389,795
Notice both answers equal 389,795
With that explanation out of the way, let's continue. Next, we take the number 389,795 and divide it by 2:
389,795 ÷ 2 = 194,897.5
If the quotient is a whole number, then 2 and 194,897.5 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 | 389,795 | |
| -1 | -389,795 |
Now, we try dividing 389,795 by 3:
389,795 ÷ 3 = 129,931.6667
If the quotient is a whole number, then 3 and 129,931.6667 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 | 389,795 | |
| -1 | -389,795 |
Let's try dividing by 4:
389,795 ÷ 4 = 97,448.75
If the quotient is a whole number, then 4 and 97,448.75 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 | 389,795 | |
| -1 | 389,795 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 37 | 43 | 49 | 185 | 215 | 245 | 259 | 301 | 1,295 | 1,505 | 1,591 | 1,813 | 2,107 | 7,955 | 9,065 | 10,535 | 11,137 | 55,685 | 77,959 | 389,795 |
| -1 | -5 | -7 | -35 | -37 | -43 | -49 | -185 | -215 | -245 | -259 | -301 | -1,295 | -1,505 | -1,591 | -1,813 | -2,107 | -7,955 | -9,065 | -10,535 | -11,137 | -55,685 | -77,959 | -389,795 |
