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 302,770,045, 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 | 302,770,045 | |
| -1 | -302,770,045 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 302,770,045.
Example:
1 x 302,770,045 = 302,770,045
and
-1 x -302,770,045 = 302,770,045
Notice both answers equal 302,770,045
With that explanation out of the way, let's continue. Next, we take the number 302,770,045 and divide it by 2:
302,770,045 ÷ 2 = 151,385,022.5
If the quotient is a whole number, then 2 and 151,385,022.5 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 | 302,770,045 | |
| -1 | -302,770,045 |
Now, we try dividing 302,770,045 by 3:
302,770,045 ÷ 3 = 100,923,348.3333
If the quotient is a whole number, then 3 and 100,923,348.3333 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 | 302,770,045 | |
| -1 | -302,770,045 |
Let's try dividing by 4:
302,770,045 ÷ 4 = 75,692,511.25
If the quotient is a whole number, then 4 and 75,692,511.25 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 | 302,770,045 | |
| -1 | 302,770,045 |
If you did it right, you will end up with this table:
| 1 | 5 | 23 | 103 | 115 | 515 | 2,369 | 11,845 | 25,561 | 127,805 | 587,903 | 2,632,783 | 2,939,515 | 13,163,915 | 60,554,009 | 302,770,045 |
| -1 | -5 | -23 | -103 | -115 | -515 | -2,369 | -11,845 | -25,561 | -127,805 | -587,903 | -2,632,783 | -2,939,515 | -13,163,915 | -60,554,009 | -302,770,045 |
