Question

what is the hcf of smallast prove number and composit number

Answer 1

Smallest prime number is 2

Prime factorisation of 2 = 2 × 1

Smallest composite number is 4

Prime factorisation of 4 = 2 × 2

So,

HCF ( 2, 4) = 2

Answer 2

Smallest composite no. Is 4
Smallest prime no. Is 2
4=2×2
2=2×1
HCF =2
