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 103,022,123, 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 | 103,022,123 | |
| -1 | -103,022,123 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,022,123.
Example:
1 x 103,022,123 = 103,022,123
and
-1 x -103,022,123 = 103,022,123
Notice both answers equal 103,022,123
With that explanation out of the way, let's continue. Next, we take the number 103,022,123 and divide it by 2:
103,022,123 ÷ 2 = 51,511,061.5
If the quotient is a whole number, then 2 and 51,511,061.5 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 | 103,022,123 | |
| -1 | -103,022,123 |
Now, we try dividing 103,022,123 by 3:
103,022,123 ÷ 3 = 34,340,707.6667
If the quotient is a whole number, then 3 and 34,340,707.6667 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 | 103,022,123 | |
| -1 | -103,022,123 |
Let's try dividing by 4:
103,022,123 ÷ 4 = 25,755,530.75
If the quotient is a whole number, then 4 and 25,755,530.75 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 | 103,022,123 | |
| -1 | 103,022,123 |
If you did it right, you will end up with this table:
| 1 | 19 | 29 | 181 | 551 | 1,033 | 3,439 | 5,249 | 19,627 | 29,957 | 99,731 | 186,973 | 569,183 | 3,552,487 | 5,422,217 | 103,022,123 |
| -1 | -19 | -29 | -181 | -551 | -1,033 | -3,439 | -5,249 | -19,627 | -29,957 | -99,731 | -186,973 | -569,183 | -3,552,487 | -5,422,217 | -103,022,123 |
