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 343,602,047, 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 | 343,602,047 | |
| -1 | -343,602,047 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 343,602,047.
Example:
1 x 343,602,047 = 343,602,047
and
-1 x -343,602,047 = 343,602,047
Notice both answers equal 343,602,047
With that explanation out of the way, let's continue. Next, we take the number 343,602,047 and divide it by 2:
343,602,047 ÷ 2 = 171,801,023.5
If the quotient is a whole number, then 2 and 171,801,023.5 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 | 343,602,047 | |
| -1 | -343,602,047 |
Now, we try dividing 343,602,047 by 3:
343,602,047 ÷ 3 = 114,534,015.6667
If the quotient is a whole number, then 3 and 114,534,015.6667 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 | 343,602,047 | |
| -1 | -343,602,047 |
Let's try dividing by 4:
343,602,047 ÷ 4 = 85,900,511.75
If the quotient is a whole number, then 4 and 85,900,511.75 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 | 343,602,047 | |
| -1 | 343,602,047 |
If you did it right, you will end up with this table:
| 1 | 31 | 79 | 173 | 811 | 2,449 | 5,363 | 13,667 | 25,141 | 64,069 | 140,303 | 423,677 | 1,986,139 | 4,349,393 | 11,083,937 | 343,602,047 |
| -1 | -31 | -79 | -173 | -811 | -2,449 | -5,363 | -13,667 | -25,141 | -64,069 | -140,303 | -423,677 | -1,986,139 | -4,349,393 | -11,083,937 | -343,602,047 |
