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 100,302,433, 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 | 100,302,433 | |
| -1 | -100,302,433 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 100,302,433.
Example:
1 x 100,302,433 = 100,302,433
and
-1 x -100,302,433 = 100,302,433
Notice both answers equal 100,302,433
With that explanation out of the way, let's continue. Next, we take the number 100,302,433 and divide it by 2:
100,302,433 ÷ 2 = 50,151,216.5
If the quotient is a whole number, then 2 and 50,151,216.5 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 | 100,302,433 | |
| -1 | -100,302,433 |
Now, we try dividing 100,302,433 by 3:
100,302,433 ÷ 3 = 33,434,144.3333
If the quotient is a whole number, then 3 and 33,434,144.3333 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 | 100,302,433 | |
| -1 | -100,302,433 |
Let's try dividing by 4:
100,302,433 ÷ 4 = 25,075,608.25
If the quotient is a whole number, then 4 and 25,075,608.25 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 | 100,302,433 | |
| -1 | 100,302,433 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 157 | 1,099 | 1,727 | 8,297 | 12,089 | 58,079 | 91,267 | 638,869 | 1,302,629 | 9,118,403 | 14,328,919 | 100,302,433 |
| -1 | -7 | -11 | -77 | -157 | -1,099 | -1,727 | -8,297 | -12,089 | -58,079 | -91,267 | -638,869 | -1,302,629 | -9,118,403 | -14,328,919 | -100,302,433 |
