The Ratio of LCM and HCF of the Least Composite And the Least Prime Numbers Is - Simple Paper

The ratio of LCM and HCF of the least composite and the least prime numbers is 
(a) 1:2
(b) 2:1
(c) 1:1
(d) 1:3

(b) 2:1

Explanation:

Least Composite Number = 4

Least Composite Number = 2

LCM of 4 and 2 = 4

HCF of 4 and 2 = 2

Thus, Ratio of LCM AND HCF = `"LCM"/"HCF"` = `frac{4}{2}` = = `frac{2}{1}`

Thus, Required Ratio is = 2:1.
