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 320,112,347, 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 | 320,112,347 | |
| -1 | -320,112,347 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 320,112,347.
Example:
1 x 320,112,347 = 320,112,347
and
-1 x -320,112,347 = 320,112,347
Notice both answers equal 320,112,347
With that explanation out of the way, let's continue. Next, we take the number 320,112,347 and divide it by 2:
320,112,347 ÷ 2 = 160,056,173.5
If the quotient is a whole number, then 2 and 160,056,173.5 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 | 320,112,347 | |
| -1 | -320,112,347 |
Now, we try dividing 320,112,347 by 3:
320,112,347 ÷ 3 = 106,704,115.6667
If the quotient is a whole number, then 3 and 106,704,115.6667 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 | 320,112,347 | |
| -1 | -320,112,347 |
Let's try dividing by 4:
320,112,347 ÷ 4 = 80,028,086.75
If the quotient is a whole number, then 4 and 80,028,086.75 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 | 320,112,347 | |
| -1 | 320,112,347 |
If you did it right, you will end up with this table:
| 1 | 47 | 59 | 241 | 479 | 2,773 | 11,327 | 14,219 | 22,513 | 28,261 | 115,439 | 668,293 | 1,328,267 | 5,425,633 | 6,810,901 | 320,112,347 |
| -1 | -47 | -59 | -241 | -479 | -2,773 | -11,327 | -14,219 | -22,513 | -28,261 | -115,439 | -668,293 | -1,328,267 | -5,425,633 | -6,810,901 | -320,112,347 |
