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 300,066,565, 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 | 300,066,565 | |
| -1 | -300,066,565 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 300,066,565.
Example:
1 x 300,066,565 = 300,066,565
and
-1 x -300,066,565 = 300,066,565
Notice both answers equal 300,066,565
With that explanation out of the way, let's continue. Next, we take the number 300,066,565 and divide it by 2:
300,066,565 ÷ 2 = 150,033,282.5
If the quotient is a whole number, then 2 and 150,033,282.5 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 | 300,066,565 | |
| -1 | -300,066,565 |
Now, we try dividing 300,066,565 by 3:
300,066,565 ÷ 3 = 100,022,188.3333
If the quotient is a whole number, then 3 and 100,022,188.3333 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 | 300,066,565 | |
| -1 | -300,066,565 |
Let's try dividing by 4:
300,066,565 ÷ 4 = 75,016,641.25
If the quotient is a whole number, then 4 and 75,016,641.25 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 | 300,066,565 | |
| -1 | 300,066,565 |
If you did it right, you will end up with this table:
| 1 | 5 | 47 | 235 | 613 | 2,083 | 3,065 | 10,415 | 28,811 | 97,901 | 144,055 | 489,505 | 1,276,879 | 6,384,395 | 60,013,313 | 300,066,565 |
| -1 | -5 | -47 | -235 | -613 | -2,083 | -3,065 | -10,415 | -28,811 | -97,901 | -144,055 | -489,505 | -1,276,879 | -6,384,395 | -60,013,313 | -300,066,565 |
