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 103,112,147, 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 | 103,112,147 | |
-1 | -103,112,147 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 103,112,147.
Example:
1 x 103,112,147 = 103,112,147
and
-1 x -103,112,147 = 103,112,147
Notice both answers equal 103,112,147
With that explanation out of the way, let's continue. Next, we take the number 103,112,147 and divide it by 2:
103,112,147 ÷ 2 = 51,556,073.5
If the quotient is a whole number, then 2 and 51,556,073.5 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 | 103,112,147 | |
-1 | -103,112,147 |
Now, we try dividing 103,112,147 by 3:
103,112,147 ÷ 3 = 34,370,715.6667
If the quotient is a whole number, then 3 and 34,370,715.6667 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 | 103,112,147 | |
-1 | -103,112,147 |
Let's try dividing by 4:
103,112,147 ÷ 4 = 25,778,036.75
If the quotient is a whole number, then 4 and 25,778,036.75 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 | 103,112,147 | |
-1 | 103,112,147 |
If you did it right, you will end up with this table:
1 | 109 | 945,983 | 103,112,147 |
-1 | -109 | -945,983 | -103,112,147 |
