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 313,520,195, 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 | 313,520,195 | |
| -1 | -313,520,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 313,520,195.
Example:
1 x 313,520,195 = 313,520,195
and
-1 x -313,520,195 = 313,520,195
Notice both answers equal 313,520,195
With that explanation out of the way, let's continue. Next, we take the number 313,520,195 and divide it by 2:
313,520,195 ÷ 2 = 156,760,097.5
If the quotient is a whole number, then 2 and 156,760,097.5 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 | 313,520,195 | |
| -1 | -313,520,195 |
Now, we try dividing 313,520,195 by 3:
313,520,195 ÷ 3 = 104,506,731.6667
If the quotient is a whole number, then 3 and 104,506,731.6667 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 | 313,520,195 | |
| -1 | -313,520,195 |
Let's try dividing by 4:
313,520,195 ÷ 4 = 78,380,048.75
If the quotient is a whole number, then 4 and 78,380,048.75 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 | 313,520,195 | |
| -1 | 313,520,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 113 | 523 | 565 | 1,061 | 2,615 | 5,305 | 59,099 | 119,893 | 295,495 | 554,903 | 599,465 | 2,774,515 | 62,704,039 | 313,520,195 |
| -1 | -5 | -113 | -523 | -565 | -1,061 | -2,615 | -5,305 | -59,099 | -119,893 | -295,495 | -554,903 | -599,465 | -2,774,515 | -62,704,039 | -313,520,195 |
