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 317,556,349, 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 | 317,556,349 | |
| -1 | -317,556,349 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 317,556,349.
Example:
1 x 317,556,349 = 317,556,349
and
-1 x -317,556,349 = 317,556,349
Notice both answers equal 317,556,349
With that explanation out of the way, let's continue. Next, we take the number 317,556,349 and divide it by 2:
317,556,349 ÷ 2 = 158,778,174.5
If the quotient is a whole number, then 2 and 158,778,174.5 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 | 317,556,349 | |
| -1 | -317,556,349 |
Now, we try dividing 317,556,349 by 3:
317,556,349 ÷ 3 = 105,852,116.3333
If the quotient is a whole number, then 3 and 105,852,116.3333 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 | 317,556,349 | |
| -1 | -317,556,349 |
Let's try dividing by 4:
317,556,349 ÷ 4 = 79,389,087.25
If the quotient is a whole number, then 4 and 79,389,087.25 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 | 317,556,349 | |
| -1 | 317,556,349 |
If you did it right, you will end up with this table:
| 1 | 11 | 59 | 67 | 109 | 649 | 737 | 1,199 | 3,953 | 4,489 | 6,431 | 7,303 | 43,483 | 49,379 | 70,741 | 80,333 | 264,851 | 430,877 | 489,301 | 2,913,361 | 4,739,647 | 5,382,311 | 28,868,759 | 317,556,349 |
| -1 | -11 | -59 | -67 | -109 | -649 | -737 | -1,199 | -3,953 | -4,489 | -6,431 | -7,303 | -43,483 | -49,379 | -70,741 | -80,333 | -264,851 | -430,877 | -489,301 | -2,913,361 | -4,739,647 | -5,382,311 | -28,868,759 | -317,556,349 |
