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 148,137,055, 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 | 148,137,055 | |
| -1 | -148,137,055 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 148,137,055.
Example:
1 x 148,137,055 = 148,137,055
and
-1 x -148,137,055 = 148,137,055
Notice both answers equal 148,137,055
With that explanation out of the way, let's continue. Next, we take the number 148,137,055 and divide it by 2:
148,137,055 ÷ 2 = 74,068,527.5
If the quotient is a whole number, then 2 and 74,068,527.5 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 | 148,137,055 | |
| -1 | -148,137,055 |
Now, we try dividing 148,137,055 by 3:
148,137,055 ÷ 3 = 49,379,018.3333
If the quotient is a whole number, then 3 and 49,379,018.3333 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 | 148,137,055 | |
| -1 | -148,137,055 |
Let's try dividing by 4:
148,137,055 ÷ 4 = 37,034,263.75
If the quotient is a whole number, then 4 and 37,034,263.75 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 | 148,137,055 | |
| -1 | 148,137,055 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 55 | 1,471 | 1,831 | 7,355 | 9,155 | 16,181 | 20,141 | 80,905 | 100,705 | 2,693,401 | 13,467,005 | 29,627,411 | 148,137,055 |
| -1 | -5 | -11 | -55 | -1,471 | -1,831 | -7,355 | -9,155 | -16,181 | -20,141 | -80,905 | -100,705 | -2,693,401 | -13,467,005 | -29,627,411 | -148,137,055 |
