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 308,410,333, 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 | 308,410,333 | |
| -1 | -308,410,333 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 308,410,333.
Example:
1 x 308,410,333 = 308,410,333
and
-1 x -308,410,333 = 308,410,333
Notice both answers equal 308,410,333
With that explanation out of the way, let's continue. Next, we take the number 308,410,333 and divide it by 2:
308,410,333 ÷ 2 = 154,205,166.5
If the quotient is a whole number, then 2 and 154,205,166.5 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 | 308,410,333 | |
| -1 | -308,410,333 |
Now, we try dividing 308,410,333 by 3:
308,410,333 ÷ 3 = 102,803,444.3333
If the quotient is a whole number, then 3 and 102,803,444.3333 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 | 308,410,333 | |
| -1 | -308,410,333 |
Let's try dividing by 4:
308,410,333 ÷ 4 = 77,102,583.25
If the quotient is a whole number, then 4 and 77,102,583.25 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 | 308,410,333 | |
| -1 | 308,410,333 |
If you did it right, you will end up with this table:
| 1 | 7 | 11 | 77 | 193 | 1,351 | 2,123 | 14,861 | 20,753 | 145,271 | 228,283 | 1,597,981 | 4,005,329 | 28,037,303 | 44,058,619 | 308,410,333 |
| -1 | -7 | -11 | -77 | -193 | -1,351 | -2,123 | -14,861 | -20,753 | -145,271 | -228,283 | -1,597,981 | -4,005,329 | -28,037,303 | -44,058,619 | -308,410,333 |
