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 342,123,025, 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 | 342,123,025 | |
| -1 | -342,123,025 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 342,123,025.
Example:
1 x 342,123,025 = 342,123,025
and
-1 x -342,123,025 = 342,123,025
Notice both answers equal 342,123,025
With that explanation out of the way, let's continue. Next, we take the number 342,123,025 and divide it by 2:
342,123,025 ÷ 2 = 171,061,512.5
If the quotient is a whole number, then 2 and 171,061,512.5 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 | 342,123,025 | |
| -1 | -342,123,025 |
Now, we try dividing 342,123,025 by 3:
342,123,025 ÷ 3 = 114,041,008.3333
If the quotient is a whole number, then 3 and 114,041,008.3333 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 | 342,123,025 | |
| -1 | -342,123,025 |
Let's try dividing by 4:
342,123,025 ÷ 4 = 85,530,756.25
If the quotient is a whole number, then 4 and 85,530,756.25 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 | 342,123,025 | |
| -1 | 342,123,025 |
If you did it right, you will end up with this table:
| 1 | 5 | 19 | 25 | 95 | 475 | 653 | 1,103 | 3,265 | 5,515 | 12,407 | 16,325 | 20,957 | 27,575 | 62,035 | 104,785 | 310,175 | 523,925 | 720,259 | 3,601,295 | 13,684,921 | 18,006,475 | 68,424,605 | 342,123,025 |
| -1 | -5 | -19 | -25 | -95 | -475 | -653 | -1,103 | -3,265 | -5,515 | -12,407 | -16,325 | -20,957 | -27,575 | -62,035 | -104,785 | -310,175 | -523,925 | -720,259 | -3,601,295 | -13,684,921 | -18,006,475 | -68,424,605 | -342,123,025 |
