The highest factor of any positive number is the number itself.
The GCF is 1.
The GCF is 15.
You need at least two numbers to find a GCF.
There is none. All the numbers have at least 1 and themselves as factors.
Not normally because the LCM of numbers are found by multiplying their highest prime factors
It is 12. Beacause the factors of 36 are: 1,36,3,12,4,9,6 and the factors of 84 are: 1,84,7,12 12 is the highest factor that both numbers have in common.
By multiplying the highest prime factors in exponential terms found in two or more numbers
No. The two numbers have multiple common factors, the highest of which is 12.
