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 310,360,645, 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 | 310,360,645 | |
| -1 | -310,360,645 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 310,360,645.
Example:
1 x 310,360,645 = 310,360,645
and
-1 x -310,360,645 = 310,360,645
Notice both answers equal 310,360,645
With that explanation out of the way, let's continue. Next, we take the number 310,360,645 and divide it by 2:
310,360,645 ÷ 2 = 155,180,322.5
If the quotient is a whole number, then 2 and 155,180,322.5 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 | 310,360,645 | |
| -1 | -310,360,645 |
Now, we try dividing 310,360,645 by 3:
310,360,645 ÷ 3 = 103,453,548.3333
If the quotient is a whole number, then 3 and 103,453,548.3333 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 | 310,360,645 | |
| -1 | -310,360,645 |
Let's try dividing by 4:
310,360,645 ÷ 4 = 77,590,161.25
If the quotient is a whole number, then 4 and 77,590,161.25 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 | 310,360,645 | |
| -1 | 310,360,645 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 1,847 | 4,801 | 9,235 | 12,929 | 24,005 | 33,607 | 64,645 | 168,035 | 8,867,447 | 44,337,235 | 62,072,129 | 310,360,645 |
| -1 | -5 | -7 | -35 | -1,847 | -4,801 | -9,235 | -12,929 | -24,005 | -33,607 | -64,645 | -168,035 | -8,867,447 | -44,337,235 | -62,072,129 | -310,360,645 |
