Answer 1

$\rule{200}3$

$\color{red}\huge{\underline{\underline{\mathfrak{Question:-}}}}$

${\red{\bold{\text{ HCF of 20 and 30 }}}}$

$\rule{200}3$

$\color{blue}\huge{\underline{\underline{\mathfrak{Answer}}}}$

${\blue{\bold{\text{ 10 is the HCF of 20 and 30 }}}}$

$\rule{200}3$

$\color{orange}\huge{\underline{\underline{\mathfrak{Solution:-}}}}$

In the question we have to find the HCF of 20 and 30

${\red{\bold{\text{What is HCF }}}}$

$\implies$${\blue{\bold{\text{HCF is the highest common factor of 2 or more than 2 numbers. }}}}$

${\blue{\bold{\text{We will solve the question by prime factorization }}}}$

${\blue{\bold{\text{Prime factors of 20 are }}}}$2×2×5

${\blue{\bold{\text{ Prime factors of 30 are }}}}$2×3×5

${\blue{\bold{\text{The common factors are to be taken out here }}}}$

${\blue{\bold{\text{which are }}}}$2×5

${\blue{\bold{\text{}}}}$2×5=10

$\rule{200}3$

Hope it helps
