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 343,155,029, 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 | 343,155,029 | |
| -1 | -343,155,029 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 343,155,029.
Example:
1 x 343,155,029 = 343,155,029
and
-1 x -343,155,029 = 343,155,029
Notice both answers equal 343,155,029
With that explanation out of the way, let's continue. Next, we take the number 343,155,029 and divide it by 2:
343,155,029 ÷ 2 = 171,577,514.5
If the quotient is a whole number, then 2 and 171,577,514.5 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 | 343,155,029 | |
| -1 | -343,155,029 |
Now, we try dividing 343,155,029 by 3:
343,155,029 ÷ 3 = 114,385,009.6667
If the quotient is a whole number, then 3 and 114,385,009.6667 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 | 343,155,029 | |
| -1 | -343,155,029 |
Let's try dividing by 4:
343,155,029 ÷ 4 = 85,788,757.25
If the quotient is a whole number, then 4 and 85,788,757.25 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 | 343,155,029 | |
| -1 | 343,155,029 |
If you did it right, you will end up with this table:
| 1 | 7 | 19 | 133 | 1,283 | 2,011 | 8,981 | 14,077 | 24,377 | 38,209 | 170,639 | 267,463 | 2,580,113 | 18,060,791 | 49,022,147 | 343,155,029 |
| -1 | -7 | -19 | -133 | -1,283 | -2,011 | -8,981 | -14,077 | -24,377 | -38,209 | -170,639 | -267,463 | -2,580,113 | -18,060,791 | -49,022,147 | -343,155,029 |
