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 317,560,153, 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 | 317,560,153 | |
| -1 | -317,560,153 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 317,560,153.
Example:
1 x 317,560,153 = 317,560,153
and
-1 x -317,560,153 = 317,560,153
Notice both answers equal 317,560,153
With that explanation out of the way, let's continue. Next, we take the number 317,560,153 and divide it by 2:
317,560,153 ÷ 2 = 158,780,076.5
If the quotient is a whole number, then 2 and 158,780,076.5 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 | 317,560,153 | |
| -1 | -317,560,153 |
Now, we try dividing 317,560,153 by 3:
317,560,153 ÷ 3 = 105,853,384.3333
If the quotient is a whole number, then 3 and 105,853,384.3333 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 | 317,560,153 | |
| -1 | -317,560,153 |
Let's try dividing by 4:
317,560,153 ÷ 4 = 79,390,038.25
If the quotient is a whole number, then 4 and 79,390,038.25 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 | 317,560,153 | |
| -1 | 317,560,153 |
If you did it right, you will end up with this table:
| 1 | 17 | 47 | 53 | 799 | 901 | 2,491 | 7,499 | 42,347 | 127,483 | 352,453 | 397,447 | 5,991,701 | 6,756,599 | 18,680,009 | 317,560,153 |
| -1 | -17 | -47 | -53 | -799 | -901 | -2,491 | -7,499 | -42,347 | -127,483 | -352,453 | -397,447 | -5,991,701 | -6,756,599 | -18,680,009 | -317,560,153 |
