Question

9) Find the HCF and LCM of the smallest prime number and smallest composite
number​

Answer 1

Answer:

Smallest prime no. = 2

Smallest composite no. =4

LCM=4

HCF=2

Answer 2

composite no. : These numbers have more than two factors

Hence smallest composite number is 4

Prime no. These do not have any factor except 1 and the no itself.

Hence smallest prime number is 2

{ 1 is not a prime number }

Hence,

LCM of 2 and 4 = 4

HCF of 2 and 4 = 2
