12,24,(36),48,(60),72,84….
So the HCF of 60 and 36 is 12
        
             
        
        
        
As per Descartes Theorem, a polynomial of degree n (n is the highest exponent of a polynomial) has n roots (or number of zeros) be it positive, negative, real or complex.
in f(x) = x⁶ + x⁵ + x⁴ + 4x³ − 12x² + 12, the highest degree is 6, then it has 
a total of 6 zeros, positive, negative, real or complex.
        
                    
             
        
        
        
The least is 0,015
