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 342,612,125, 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 | 342,612,125 | |
| -1 | -342,612,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 342,612,125.
Example:
1 x 342,612,125 = 342,612,125
and
-1 x -342,612,125 = 342,612,125
Notice both answers equal 342,612,125
With that explanation out of the way, let's continue. Next, we take the number 342,612,125 and divide it by 2:
342,612,125 ÷ 2 = 171,306,062.5
If the quotient is a whole number, then 2 and 171,306,062.5 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 | 342,612,125 | |
| -1 | -342,612,125 |
Now, we try dividing 342,612,125 by 3:
342,612,125 ÷ 3 = 114,204,041.6667
If the quotient is a whole number, then 3 and 114,204,041.6667 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 | 342,612,125 | |
| -1 | -342,612,125 |
Let's try dividing by 4:
342,612,125 ÷ 4 = 85,653,031.25
If the quotient is a whole number, then 4 and 85,653,031.25 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 | 342,612,125 | |
| -1 | 342,612,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 125 | 1,279 | 2,143 | 6,395 | 10,715 | 31,975 | 53,575 | 159,875 | 267,875 | 2,740,897 | 13,704,485 | 68,522,425 | 342,612,125 |
| -1 | -5 | -25 | -125 | -1,279 | -2,143 | -6,395 | -10,715 | -31,975 | -53,575 | -159,875 | -267,875 | -2,740,897 | -13,704,485 | -68,522,425 | -342,612,125 |
