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 342,040,025, 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 | 342,040,025 | |
| -1 | -342,040,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 342,040,025.
Example:
1 x 342,040,025 = 342,040,025
and
-1 x -342,040,025 = 342,040,025
Notice both answers equal 342,040,025
With that explanation out of the way, let's continue. Next, we take the number 342,040,025 and divide it by 2:
342,040,025 ÷ 2 = 171,020,012.5
If the quotient is a whole number, then 2 and 171,020,012.5 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 | 342,040,025 | |
| -1 | -342,040,025 |
Now, we try dividing 342,040,025 by 3:
342,040,025 ÷ 3 = 114,013,341.6667
If the quotient is a whole number, then 3 and 114,013,341.6667 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 | 342,040,025 | |
| -1 | -342,040,025 |
Let's try dividing by 4:
342,040,025 ÷ 4 = 85,510,006.25
If the quotient is a whole number, then 4 and 85,510,006.25 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 | 342,040,025 | |
| -1 | 342,040,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 37 | 67 | 185 | 335 | 925 | 1,675 | 2,479 | 5,519 | 12,395 | 27,595 | 61,975 | 137,975 | 204,203 | 369,773 | 1,021,015 | 1,848,865 | 5,105,075 | 9,244,325 | 13,681,601 | 68,408,005 | 342,040,025 |
| -1 | -5 | -25 | -37 | -67 | -185 | -335 | -925 | -1,675 | -2,479 | -5,519 | -12,395 | -27,595 | -61,975 | -137,975 | -204,203 | -369,773 | -1,021,015 | -1,848,865 | -5,105,075 | -9,244,325 | -13,681,601 | -68,408,005 | -342,040,025 |
