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 343,344,551, 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 | 343,344,551 | |
| -1 | -343,344,551 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 343,344,551.
Example:
1 x 343,344,551 = 343,344,551
and
-1 x -343,344,551 = 343,344,551
Notice both answers equal 343,344,551
With that explanation out of the way, let's continue. Next, we take the number 343,344,551 and divide it by 2:
343,344,551 ÷ 2 = 171,672,275.5
If the quotient is a whole number, then 2 and 171,672,275.5 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 | 343,344,551 | |
| -1 | -343,344,551 |
Now, we try dividing 343,344,551 by 3:
343,344,551 ÷ 3 = 114,448,183.6667
If the quotient is a whole number, then 3 and 114,448,183.6667 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 | 343,344,551 | |
| -1 | -343,344,551 |
Let's try dividing by 4:
343,344,551 ÷ 4 = 85,836,137.75
If the quotient is a whole number, then 4 and 85,836,137.75 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 | 343,344,551 | |
| -1 | 343,344,551 |
If you did it right, you will end up with this table:
| 1 | 11 | 43 | 101 | 473 | 1,111 | 4,343 | 7,187 | 47,773 | 79,057 | 309,041 | 725,887 | 3,399,451 | 7,984,757 | 31,213,141 | 343,344,551 |
| -1 | -11 | -43 | -101 | -473 | -1,111 | -4,343 | -7,187 | -47,773 | -79,057 | -309,041 | -725,887 | -3,399,451 | -7,984,757 | -31,213,141 | -343,344,551 |
