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 147,146,135, 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 | 147,146,135 | |
| -1 | -147,146,135 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 147,146,135.
Example:
1 x 147,146,135 = 147,146,135
and
-1 x -147,146,135 = 147,146,135
Notice both answers equal 147,146,135
With that explanation out of the way, let's continue. Next, we take the number 147,146,135 and divide it by 2:
147,146,135 ÷ 2 = 73,573,067.5
If the quotient is a whole number, then 2 and 73,573,067.5 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 | 147,146,135 | |
| -1 | -147,146,135 |
Now, we try dividing 147,146,135 by 3:
147,146,135 ÷ 3 = 49,048,711.6667
If the quotient is a whole number, then 3 and 49,048,711.6667 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 | 147,146,135 | |
| -1 | -147,146,135 |
Let's try dividing by 4:
147,146,135 ÷ 4 = 36,786,533.75
If the quotient is a whole number, then 4 and 36,786,533.75 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 | 147,146,135 | |
| -1 | 147,146,135 |
If you did it right, you will end up with this table:
| 1 | 5 | 17 | 83 | 85 | 415 | 1,411 | 7,055 | 20,857 | 104,285 | 354,569 | 1,731,131 | 1,772,845 | 8,655,655 | 29,429,227 | 147,146,135 |
| -1 | -5 | -17 | -83 | -85 | -415 | -1,411 | -7,055 | -20,857 | -104,285 | -354,569 | -1,731,131 | -1,772,845 | -8,655,655 | -29,429,227 | -147,146,135 |
