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 145,133,125, 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 | 145,133,125 | |
| -1 | -145,133,125 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 145,133,125.
Example:
1 x 145,133,125 = 145,133,125
and
-1 x -145,133,125 = 145,133,125
Notice both answers equal 145,133,125
With that explanation out of the way, let's continue. Next, we take the number 145,133,125 and divide it by 2:
145,133,125 ÷ 2 = 72,566,562.5
If the quotient is a whole number, then 2 and 72,566,562.5 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 | 145,133,125 | |
| -1 | -145,133,125 |
Now, we try dividing 145,133,125 by 3:
145,133,125 ÷ 3 = 48,377,708.3333
If the quotient is a whole number, then 3 and 48,377,708.3333 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 | 145,133,125 | |
| -1 | -145,133,125 |
Let's try dividing by 4:
145,133,125 ÷ 4 = 36,283,281.25
If the quotient is a whole number, then 4 and 36,283,281.25 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 | 145,133,125 | |
| -1 | 145,133,125 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 73 | 125 | 365 | 625 | 1,825 | 3,181 | 9,125 | 15,905 | 45,625 | 79,525 | 232,213 | 397,625 | 1,161,065 | 1,988,125 | 5,805,325 | 29,026,625 | 145,133,125 |
| -1 | -5 | -25 | -73 | -125 | -365 | -625 | -1,825 | -3,181 | -9,125 | -15,905 | -45,625 | -79,525 | -232,213 | -397,625 | -1,161,065 | -1,988,125 | -5,805,325 | -29,026,625 | -145,133,125 |
