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 343,033,015, 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 | 343,033,015 | |
| -1 | -343,033,015 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 343,033,015.
Example:
1 x 343,033,015 = 343,033,015
and
-1 x -343,033,015 = 343,033,015
Notice both answers equal 343,033,015
With that explanation out of the way, let's continue. Next, we take the number 343,033,015 and divide it by 2:
343,033,015 ÷ 2 = 171,516,507.5
If the quotient is a whole number, then 2 and 171,516,507.5 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 | 343,033,015 | |
| -1 | -343,033,015 |
Now, we try dividing 343,033,015 by 3:
343,033,015 ÷ 3 = 114,344,338.3333
If the quotient is a whole number, then 3 and 114,344,338.3333 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 | 343,033,015 | |
| -1 | -343,033,015 |
Let's try dividing by 4:
343,033,015 ÷ 4 = 85,758,253.75
If the quotient is a whole number, then 4 and 85,758,253.75 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 | 343,033,015 | |
| -1 | 343,033,015 |
If you did it right, you will end up with this table:
| 1 | 5 | 13 | 65 | 149 | 745 | 1,937 | 9,685 | 35,419 | 177,095 | 460,447 | 2,302,235 | 5,277,431 | 26,387,155 | 68,606,603 | 343,033,015 |
| -1 | -5 | -13 | -65 | -149 | -745 | -1,937 | -9,685 | -35,419 | -177,095 | -460,447 | -2,302,235 | -5,277,431 | -26,387,155 | -68,606,603 | -343,033,015 |
