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 310,232,125, 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 | 310,232,125 | |
| -1 | -310,232,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 310,232,125.
Example:
1 x 310,232,125 = 310,232,125
and
-1 x -310,232,125 = 310,232,125
Notice both answers equal 310,232,125
With that explanation out of the way, let's continue. Next, we take the number 310,232,125 and divide it by 2:
310,232,125 ÷ 2 = 155,116,062.5
If the quotient is a whole number, then 2 and 155,116,062.5 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 | 310,232,125 | |
| -1 | -310,232,125 |
Now, we try dividing 310,232,125 by 3:
310,232,125 ÷ 3 = 103,410,708.3333
If the quotient is a whole number, then 3 and 103,410,708.3333 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 | 310,232,125 | |
| -1 | -310,232,125 |
Let's try dividing by 4:
310,232,125 ÷ 4 = 77,558,031.25
If the quotient is a whole number, then 4 and 77,558,031.25 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 | 310,232,125 | |
| -1 | 310,232,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 25 | 35 | 125 | 175 | 875 | 354,551 | 1,772,755 | 2,481,857 | 8,863,775 | 12,409,285 | 44,318,875 | 62,046,425 | 310,232,125 |
| -1 | -5 | -7 | -25 | -35 | -125 | -175 | -875 | -354,551 | -1,772,755 | -2,481,857 | -8,863,775 | -12,409,285 | -44,318,875 | -62,046,425 | -310,232,125 |
