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 150,264,265, 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 | 150,264,265 | |
| -1 | -150,264,265 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 150,264,265.
Example:
1 x 150,264,265 = 150,264,265
and
-1 x -150,264,265 = 150,264,265
Notice both answers equal 150,264,265
With that explanation out of the way, let's continue. Next, we take the number 150,264,265 and divide it by 2:
150,264,265 ÷ 2 = 75,132,132.5
If the quotient is a whole number, then 2 and 75,132,132.5 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 | 150,264,265 | |
| -1 | -150,264,265 |
Now, we try dividing 150,264,265 by 3:
150,264,265 ÷ 3 = 50,088,088.3333
If the quotient is a whole number, then 3 and 50,088,088.3333 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 | 150,264,265 | |
| -1 | -150,264,265 |
Let's try dividing by 4:
150,264,265 ÷ 4 = 37,566,066.25
If the quotient is a whole number, then 4 and 37,566,066.25 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 | 150,264,265 | |
| -1 | 150,264,265 |
If you did it right, you will end up with this table:
| 1 | 5 | 101 | 149 | 505 | 745 | 1,997 | 9,985 | 15,049 | 75,245 | 201,697 | 297,553 | 1,008,485 | 1,487,765 | 30,052,853 | 150,264,265 |
| -1 | -5 | -101 | -149 | -505 | -745 | -1,997 | -9,985 | -15,049 | -75,245 | -201,697 | -297,553 | -1,008,485 | -1,487,765 | -30,052,853 | -150,264,265 |
