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 317,652,811, 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 | 317,652,811 | |
| -1 | -317,652,811 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 317,652,811.
Example:
1 x 317,652,811 = 317,652,811
and
-1 x -317,652,811 = 317,652,811
Notice both answers equal 317,652,811
With that explanation out of the way, let's continue. Next, we take the number 317,652,811 and divide it by 2:
317,652,811 ÷ 2 = 158,826,405.5
If the quotient is a whole number, then 2 and 158,826,405.5 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 | 317,652,811 | |
| -1 | -317,652,811 |
Now, we try dividing 317,652,811 by 3:
317,652,811 ÷ 3 = 105,884,270.3333
If the quotient is a whole number, then 3 and 105,884,270.3333 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 | 317,652,811 | |
| -1 | -317,652,811 |
Let's try dividing by 4:
317,652,811 ÷ 4 = 79,413,202.75
If the quotient is a whole number, then 4 and 79,413,202.75 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 | 317,652,811 | |
| -1 | 317,652,811 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 151 | 1,057 | 2,869 | 15,817 | 20,083 | 110,719 | 300,523 | 2,103,661 | 2,388,367 | 16,718,569 | 45,378,973 | 317,652,811 |
| -1 | -7 | -19 | -133 | -151 | -1,057 | -2,869 | -15,817 | -20,083 | -110,719 | -300,523 | -2,103,661 | -2,388,367 | -16,718,569 | -45,378,973 | -317,652,811 |
