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 342,012,143, 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 | 342,012,143 | |
| -1 | -342,012,143 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 342,012,143.
Example:
1 x 342,012,143 = 342,012,143
and
-1 x -342,012,143 = 342,012,143
Notice both answers equal 342,012,143
With that explanation out of the way, let's continue. Next, we take the number 342,012,143 and divide it by 2:
342,012,143 ÷ 2 = 171,006,071.5
If the quotient is a whole number, then 2 and 171,006,071.5 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 | 342,012,143 | |
| -1 | -342,012,143 |
Now, we try dividing 342,012,143 by 3:
342,012,143 ÷ 3 = 114,004,047.6667
If the quotient is a whole number, then 3 and 114,004,047.6667 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 | 342,012,143 | |
| -1 | -342,012,143 |
Let's try dividing by 4:
342,012,143 ÷ 4 = 85,503,035.75
If the quotient is a whole number, then 4 and 85,503,035.75 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 | 342,012,143 | |
| -1 | 342,012,143 |
If you did it right, you will end up with this table:
| 1 | 11 | 127 | 137 | 1,397 | 1,507 | 1,787 | 17,399 | 19,657 | 191,389 | 226,949 | 244,819 | 2,496,439 | 2,693,009 | 31,092,013 | 342,012,143 |
| -1 | -11 | -127 | -137 | -1,397 | -1,507 | -1,787 | -17,399 | -19,657 | -191,389 | -226,949 | -244,819 | -2,496,439 | -2,693,009 | -31,092,013 | -342,012,143 |
