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 342,013,103, 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 | 342,013,103 | |
| -1 | -342,013,103 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 342,013,103.
Example:
1 x 342,013,103 = 342,013,103
and
-1 x -342,013,103 = 342,013,103
Notice both answers equal 342,013,103
With that explanation out of the way, let's continue. Next, we take the number 342,013,103 and divide it by 2:
342,013,103 ÷ 2 = 171,006,551.5
If the quotient is a whole number, then 2 and 171,006,551.5 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 | 342,013,103 | |
| -1 | -342,013,103 |
Now, we try dividing 342,013,103 by 3:
342,013,103 ÷ 3 = 114,004,367.6667
If the quotient is a whole number, then 3 and 114,004,367.6667 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 | 342,013,103 | |
| -1 | -342,013,103 |
Let's try dividing by 4:
342,013,103 ÷ 4 = 85,503,275.75
If the quotient is a whole number, then 4 and 85,503,275.75 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 | 342,013,103 | |
| -1 | 342,013,103 |
If you did it right, you will end up with this table:
| 1 | 41 | 73 | 229 | 499 | 2,993 | 9,389 | 16,717 | 20,459 | 36,427 | 114,271 | 685,397 | 1,493,507 | 4,685,111 | 8,341,783 | 342,013,103 |
| -1 | -41 | -73 | -229 | -499 | -2,993 | -9,389 | -16,717 | -20,459 | -36,427 | -114,271 | -685,397 | -1,493,507 | -4,685,111 | -8,341,783 | -342,013,103 |
