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 148,050,455, 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 | 148,050,455 | |
| -1 | -148,050,455 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 148,050,455.
Example:
1 x 148,050,455 = 148,050,455
and
-1 x -148,050,455 = 148,050,455
Notice both answers equal 148,050,455
With that explanation out of the way, let's continue. Next, we take the number 148,050,455 and divide it by 2:
148,050,455 ÷ 2 = 74,025,227.5
If the quotient is a whole number, then 2 and 74,025,227.5 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 | 148,050,455 | |
| -1 | -148,050,455 |
Now, we try dividing 148,050,455 by 3:
148,050,455 ÷ 3 = 49,350,151.6667
If the quotient is a whole number, then 3 and 49,350,151.6667 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 | 148,050,455 | |
| -1 | -148,050,455 |
Let's try dividing by 4:
148,050,455 ÷ 4 = 37,012,613.75
If the quotient is a whole number, then 4 and 37,012,613.75 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 | 148,050,455 | |
| -1 | 148,050,455 |
If you did it right, you will end up with this table:
| 1 | 5 | 7 | 35 | 163 | 815 | 1,141 | 5,705 | 25,951 | 129,755 | 181,657 | 908,285 | 4,230,013 | 21,150,065 | 29,610,091 | 148,050,455 |
| -1 | -5 | -7 | -35 | -163 | -815 | -1,141 | -5,705 | -25,951 | -129,755 | -181,657 | -908,285 | -4,230,013 | -21,150,065 | -29,610,091 | -148,050,455 |
