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 103,808,719, 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 | 103,808,719 | |
| -1 | -103,808,719 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,808,719.
Example:
1 x 103,808,719 = 103,808,719
and
-1 x -103,808,719 = 103,808,719
Notice both answers equal 103,808,719
With that explanation out of the way, let's continue. Next, we take the number 103,808,719 and divide it by 2:
103,808,719 ÷ 2 = 51,904,359.5
If the quotient is a whole number, then 2 and 51,904,359.5 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 | 103,808,719 | |
| -1 | -103,808,719 |
Now, we try dividing 103,808,719 by 3:
103,808,719 ÷ 3 = 34,602,906.3333
If the quotient is a whole number, then 3 and 34,602,906.3333 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 | 103,808,719 | |
| -1 | -103,808,719 |
Let's try dividing by 4:
103,808,719 ÷ 4 = 25,952,179.75
If the quotient is a whole number, then 4 and 25,952,179.75 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 | 103,808,719 | |
| -1 | 103,808,719 |
If you did it right, you will end up with this table:
| 1 | 7 | 29 | 203 | 433 | 1,181 | 3,031 | 8,267 | 12,557 | 34,249 | 87,899 | 239,743 | 511,373 | 3,579,611 | 14,829,817 | 103,808,719 |
| -1 | -7 | -29 | -203 | -433 | -1,181 | -3,031 | -8,267 | -12,557 | -34,249 | -87,899 | -239,743 | -511,373 | -3,579,611 | -14,829,817 | -103,808,719 |
