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 300,356,045, 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 | 300,356,045 | |
| -1 | -300,356,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 300,356,045.
Example:
1 x 300,356,045 = 300,356,045
and
-1 x -300,356,045 = 300,356,045
Notice both answers equal 300,356,045
With that explanation out of the way, let's continue. Next, we take the number 300,356,045 and divide it by 2:
300,356,045 ÷ 2 = 150,178,022.5
If the quotient is a whole number, then 2 and 150,178,022.5 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 | 300,356,045 | |
| -1 | -300,356,045 |
Now, we try dividing 300,356,045 by 3:
300,356,045 ÷ 3 = 100,118,681.6667
If the quotient is a whole number, then 3 and 100,118,681.6667 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 | 300,356,045 | |
| -1 | -300,356,045 |
Let's try dividing by 4:
300,356,045 ÷ 4 = 75,089,011.25
If the quotient is a whole number, then 4 and 75,089,011.25 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 | 300,356,045 | |
| -1 | 300,356,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 11 | 29 | 55 | 145 | 319 | 1,595 | 188,311 | 941,555 | 2,071,421 | 5,461,019 | 10,357,105 | 27,305,095 | 60,071,209 | 300,356,045 |
| -1 | -5 | -11 | -29 | -55 | -145 | -319 | -1,595 | -188,311 | -941,555 | -2,071,421 | -5,461,019 | -10,357,105 | -27,305,095 | -60,071,209 | -300,356,045 |
