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 135,147,275, 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 | 135,147,275 | |
| -1 | -135,147,275 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 135,147,275.
Example:
1 x 135,147,275 = 135,147,275
and
-1 x -135,147,275 = 135,147,275
Notice both answers equal 135,147,275
With that explanation out of the way, let's continue. Next, we take the number 135,147,275 and divide it by 2:
135,147,275 ÷ 2 = 67,573,637.5
If the quotient is a whole number, then 2 and 67,573,637.5 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 | 135,147,275 | |
| -1 | -135,147,275 |
Now, we try dividing 135,147,275 by 3:
135,147,275 ÷ 3 = 45,049,091.6667
If the quotient is a whole number, then 3 and 45,049,091.6667 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 | 135,147,275 | |
| -1 | -135,147,275 |
Let's try dividing by 4:
135,147,275 ÷ 4 = 33,786,818.75
If the quotient is a whole number, then 4 and 33,786,818.75 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 | 135,147,275 | |
| -1 | 135,147,275 |
If you did it right, you will end up with this table:
| 1 | 5 | 25 | 41 | 79 | 205 | 395 | 1,025 | 1,669 | 1,975 | 3,239 | 8,345 | 16,195 | 41,725 | 68,429 | 80,975 | 131,851 | 342,145 | 659,255 | 1,710,725 | 3,296,275 | 5,405,891 | 27,029,455 | 135,147,275 |
| -1 | -5 | -25 | -41 | -79 | -205 | -395 | -1,025 | -1,669 | -1,975 | -3,239 | -8,345 | -16,195 | -41,725 | -68,429 | -80,975 | -131,851 | -342,145 | -659,255 | -1,710,725 | -3,296,275 | -5,405,891 | -27,029,455 | -135,147,275 |
