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 343,244,431, 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 | 343,244,431 | |
| -1 | -343,244,431 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 343,244,431.
Example:
1 x 343,244,431 = 343,244,431
and
-1 x -343,244,431 = 343,244,431
Notice both answers equal 343,244,431
With that explanation out of the way, let's continue. Next, we take the number 343,244,431 and divide it by 2:
343,244,431 ÷ 2 = 171,622,215.5
If the quotient is a whole number, then 2 and 171,622,215.5 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 | 343,244,431 | |
| -1 | -343,244,431 |
Now, we try dividing 343,244,431 by 3:
343,244,431 ÷ 3 = 114,414,810.3333
If the quotient is a whole number, then 3 and 114,414,810.3333 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 | 343,244,431 | |
| -1 | -343,244,431 |
Let's try dividing by 4:
343,244,431 ÷ 4 = 85,811,107.75
If the quotient is a whole number, then 4 and 85,811,107.75 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 | 343,244,431 | |
| -1 | 343,244,431 |
If you did it right, you will end up with this table:
| 1 | 31 | 47 | 89 | 1,457 | 2,647 | 2,759 | 4,183 | 82,057 | 124,409 | 129,673 | 235,583 | 3,856,679 | 7,303,073 | 11,072,401 | 343,244,431 |
| -1 | -31 | -47 | -89 | -1,457 | -2,647 | -2,759 | -4,183 | -82,057 | -124,409 | -129,673 | -235,583 | -3,856,679 | -7,303,073 | -11,072,401 | -343,244,431 |
