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 300,653,065, 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 | 300,653,065 | |
| -1 | -300,653,065 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 300,653,065.
Example:
1 x 300,653,065 = 300,653,065
and
-1 x -300,653,065 = 300,653,065
Notice both answers equal 300,653,065
With that explanation out of the way, let's continue. Next, we take the number 300,653,065 and divide it by 2:
300,653,065 ÷ 2 = 150,326,532.5
If the quotient is a whole number, then 2 and 150,326,532.5 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 | 300,653,065 | |
| -1 | -300,653,065 |
Now, we try dividing 300,653,065 by 3:
300,653,065 ÷ 3 = 100,217,688.3333
If the quotient is a whole number, then 3 and 100,217,688.3333 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 | 300,653,065 | |
| -1 | -300,653,065 |
Let's try dividing by 4:
300,653,065 ÷ 4 = 75,163,266.25
If the quotient is a whole number, then 4 and 75,163,266.25 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 | 300,653,065 | |
| -1 | 300,653,065 |
If you did it right, you will end up with this table:
| 1 | 5 | 79 | 109 | 395 | 545 | 6,983 | 8,611 | 34,915 | 43,055 | 551,657 | 761,147 | 2,758,285 | 3,805,735 | 60,130,613 | 300,653,065 |
| -1 | -5 | -79 | -109 | -395 | -545 | -6,983 | -8,611 | -34,915 | -43,055 | -551,657 | -761,147 | -2,758,285 | -3,805,735 | -60,130,613 | -300,653,065 |
