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 303,012,445, 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 | 303,012,445 | |
| -1 | -303,012,445 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 303,012,445.
Example:
1 x 303,012,445 = 303,012,445
and
-1 x -303,012,445 = 303,012,445
Notice both answers equal 303,012,445
With that explanation out of the way, let's continue. Next, we take the number 303,012,445 and divide it by 2:
303,012,445 ÷ 2 = 151,506,222.5
If the quotient is a whole number, then 2 and 151,506,222.5 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 | 303,012,445 | |
| -1 | -303,012,445 |
Now, we try dividing 303,012,445 by 3:
303,012,445 ÷ 3 = 101,004,148.3333
If the quotient is a whole number, then 3 and 101,004,148.3333 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 | 303,012,445 | |
| -1 | -303,012,445 |
Let's try dividing by 4:
303,012,445 ÷ 4 = 75,753,111.25
If the quotient is a whole number, then 4 and 75,753,111.25 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 | 303,012,445 | |
| -1 | 303,012,445 |
If you did it right, you will end up with this table:
| 1 | 5 | 29 | 31 | 145 | 155 | 899 | 4,495 | 67,411 | 337,055 | 1,954,919 | 2,089,741 | 9,774,595 | 10,448,705 | 60,602,489 | 303,012,445 |
| -1 | -5 | -29 | -31 | -145 | -155 | -899 | -4,495 | -67,411 | -337,055 | -1,954,919 | -2,089,741 | -9,774,595 | -10,448,705 | -60,602,489 | -303,012,445 |
