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 134,145,125, 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 | 134,145,125 | |
| -1 | -134,145,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 134,145,125.
Example:
1 x 134,145,125 = 134,145,125
and
-1 x -134,145,125 = 134,145,125
Notice both answers equal 134,145,125
With that explanation out of the way, let's continue. Next, we take the number 134,145,125 and divide it by 2:
134,145,125 ÷ 2 = 67,072,562.5
If the quotient is a whole number, then 2 and 67,072,562.5 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 | 134,145,125 | |
| -1 | -134,145,125 |
Now, we try dividing 134,145,125 by 3:
134,145,125 ÷ 3 = 44,715,041.6667
If the quotient is a whole number, then 3 and 44,715,041.6667 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 | 134,145,125 | |
| -1 | -134,145,125 |
Let's try dividing by 4:
134,145,125 ÷ 4 = 33,536,281.25
If the quotient is a whole number, then 4 and 33,536,281.25 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 | 134,145,125 | |
| -1 | 134,145,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 113 | 125 | 565 | 2,825 | 9,497 | 14,125 | 47,485 | 237,425 | 1,073,161 | 1,187,125 | 5,365,805 | 26,829,025 | 134,145,125 |
| -1 | -5 | -25 | -113 | -125 | -565 | -2,825 | -9,497 | -14,125 | -47,485 | -237,425 | -1,073,161 | -1,187,125 | -5,365,805 | -26,829,025 | -134,145,125 |
