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 315,341,155, 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 | 315,341,155 | |
| -1 | -315,341,155 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 315,341,155.
Example:
1 x 315,341,155 = 315,341,155
and
-1 x -315,341,155 = 315,341,155
Notice both answers equal 315,341,155
With that explanation out of the way, let's continue. Next, we take the number 315,341,155 and divide it by 2:
315,341,155 ÷ 2 = 157,670,577.5
If the quotient is a whole number, then 2 and 157,670,577.5 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 | 315,341,155 | |
| -1 | -315,341,155 |
Now, we try dividing 315,341,155 by 3:
315,341,155 ÷ 3 = 105,113,718.3333
If the quotient is a whole number, then 3 and 105,113,718.3333 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 | 315,341,155 | |
| -1 | -315,341,155 |
Let's try dividing by 4:
315,341,155 ÷ 4 = 78,835,288.75
If the quotient is a whole number, then 4 and 78,835,288.75 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 | 315,341,155 | |
| -1 | 315,341,155 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 115 | 991 | 2,767 | 4,955 | 13,835 | 22,793 | 63,641 | 113,965 | 318,205 | 2,742,097 | 13,710,485 | 63,068,231 | 315,341,155 |
| -1 | -5 | -23 | -115 | -991 | -2,767 | -4,955 | -13,835 | -22,793 | -63,641 | -113,965 | -318,205 | -2,742,097 | -13,710,485 | -63,068,231 | -315,341,155 |
