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 135,251,201, 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 | 135,251,201 | |
| -1 | -135,251,201 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 135,251,201.
Example:
1 x 135,251,201 = 135,251,201
and
-1 x -135,251,201 = 135,251,201
Notice both answers equal 135,251,201
With that explanation out of the way, let's continue. Next, we take the number 135,251,201 and divide it by 2:
135,251,201 ÷ 2 = 67,625,600.5
If the quotient is a whole number, then 2 and 67,625,600.5 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 | 135,251,201 | |
| -1 | -135,251,201 |
Now, we try dividing 135,251,201 by 3:
135,251,201 ÷ 3 = 45,083,733.6667
If the quotient is a whole number, then 3 and 45,083,733.6667 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 | 135,251,201 | |
| -1 | -135,251,201 |
Let's try dividing by 4:
135,251,201 ÷ 4 = 33,812,800.25
If the quotient is a whole number, then 4 and 33,812,800.25 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 | 135,251,201 | |
| -1 | 135,251,201 |
If you did it right, you will end up with this table:
| 1 | 17 | 23 | 281 | 391 | 1,231 | 4,777 | 6,463 | 20,927 | 28,313 | 109,871 | 345,911 | 481,321 | 5,880,487 | 7,955,953 | 135,251,201 |
| -1 | -17 | -23 | -281 | -391 | -1,231 | -4,777 | -6,463 | -20,927 | -28,313 | -109,871 | -345,911 | -481,321 | -5,880,487 | -7,955,953 | -135,251,201 |
