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 313,544,455, 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 | 313,544,455 | |
| -1 | -313,544,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 313,544,455.
Example:
1 x 313,544,455 = 313,544,455
and
-1 x -313,544,455 = 313,544,455
Notice both answers equal 313,544,455
With that explanation out of the way, let's continue. Next, we take the number 313,544,455 and divide it by 2:
313,544,455 ÷ 2 = 156,772,227.5
If the quotient is a whole number, then 2 and 156,772,227.5 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 | 313,544,455 | |
| -1 | -313,544,455 |
Now, we try dividing 313,544,455 by 3:
313,544,455 ÷ 3 = 104,514,818.3333
If the quotient is a whole number, then 3 and 104,514,818.3333 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 | 313,544,455 | |
| -1 | -313,544,455 |
Let's try dividing by 4:
313,544,455 ÷ 4 = 78,386,113.75
If the quotient is a whole number, then 4 and 78,386,113.75 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 | 313,544,455 | |
| -1 | 313,544,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 179 | 895 | 1,253 | 6,265 | 50,047 | 250,235 | 350,329 | 1,751,645 | 8,958,413 | 44,792,065 | 62,708,891 | 313,544,455 |
| -1 | -5 | -7 | -35 | -179 | -895 | -1,253 | -6,265 | -50,047 | -250,235 | -350,329 | -1,751,645 | -8,958,413 | -44,792,065 | -62,708,891 | -313,544,455 |
