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 135,251,195, 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 | 135,251,195 | |
| -1 | -135,251,195 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 135,251,195.
Example:
1 x 135,251,195 = 135,251,195
and
-1 x -135,251,195 = 135,251,195
Notice both answers equal 135,251,195
With that explanation out of the way, let's continue. Next, we take the number 135,251,195 and divide it by 2:
135,251,195 ÷ 2 = 67,625,597.5
If the quotient is a whole number, then 2 and 67,625,597.5 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 | 135,251,195 | |
| -1 | -135,251,195 |
Now, we try dividing 135,251,195 by 3:
135,251,195 ÷ 3 = 45,083,731.6667
If the quotient is a whole number, then 3 and 45,083,731.6667 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 | 135,251,195 | |
| -1 | -135,251,195 |
Let's try dividing by 4:
135,251,195 ÷ 4 = 33,812,798.75
If the quotient is a whole number, then 4 and 33,812,798.75 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 | 135,251,195 | |
| -1 | 135,251,195 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 137 | 235 | 685 | 4,201 | 6,439 | 21,005 | 32,195 | 197,447 | 575,537 | 987,235 | 2,877,685 | 27,050,239 | 135,251,195 |
| -1 | -5 | -47 | -137 | -235 | -685 | -4,201 | -6,439 | -21,005 | -32,195 | -197,447 | -575,537 | -987,235 | -2,877,685 | -27,050,239 | -135,251,195 |
