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 5,147,447, 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 | 5,147,447 | |
-1 | -5,147,447 |
When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 5,147,447.
Example:
1 x 5,147,447 = 5,147,447
and
-1 x -5,147,447 = 5,147,447
Notice both answers equal 5,147,447
With that explanation out of the way, let's continue. Next, we take the number 5,147,447 and divide it by 2:
5,147,447 ÷ 2 = 2,573,723.5
If the quotient is a whole number, then 2 and 2,573,723.5 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 | 5,147,447 | |
-1 | -5,147,447 |
Now, we try dividing 5,147,447 by 3:
5,147,447 ÷ 3 = 1,715,815.6667
If the quotient is a whole number, then 3 and 1,715,815.6667 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 | 5,147,447 | |
-1 | -5,147,447 |
Let's try dividing by 4:
5,147,447 ÷ 4 = 1,286,861.75
If the quotient is a whole number, then 4 and 1,286,861.75 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 | 5,147,447 | |
-1 | 5,147,447 |
If you did it right, you will end up with this table:
1 | 17 | 302,791 | 5,147,447 |
-1 | -17 | -302,791 | -5,147,447 |
