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 320,014,069, 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 | 320,014,069 | |
| -1 | -320,014,069 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 320,014,069.
Example:
1 x 320,014,069 = 320,014,069
and
-1 x -320,014,069 = 320,014,069
Notice both answers equal 320,014,069
With that explanation out of the way, let's continue. Next, we take the number 320,014,069 and divide it by 2:
320,014,069 ÷ 2 = 160,007,034.5
If the quotient is a whole number, then 2 and 160,007,034.5 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 | 320,014,069 | |
| -1 | -320,014,069 |
Now, we try dividing 320,014,069 by 3:
320,014,069 ÷ 3 = 106,671,356.3333
If the quotient is a whole number, then 3 and 106,671,356.3333 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 | 320,014,069 | |
| -1 | -320,014,069 |
Let's try dividing by 4:
320,014,069 ÷ 4 = 80,003,517.25
If the quotient is a whole number, then 4 and 80,003,517.25 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 | 320,014,069 | |
| -1 | 320,014,069 |
If you did it right, you will end up with this table:
| 1 | 17 | 79 | 239 | 997 | 1,343 | 4,063 | 16,949 | 18,881 | 78,763 | 238,283 | 320,977 | 1,338,971 | 4,050,811 | 18,824,357 | 320,014,069 |
| -1 | -17 | -79 | -239 | -997 | -1,343 | -4,063 | -16,949 | -18,881 | -78,763 | -238,283 | -320,977 | -1,338,971 | -4,050,811 | -18,824,357 | -320,014,069 |
