Question

What is the HCF of 24, 36& 48?

Answer 1

it's HCF is 12 the highest factor
the factor of 24 are 12 and 2
the factor of 36 are 12 and 3
the factor of 48 are 12 and 2 and 2
hence 12 is highest factor common

Answer 2

Step1:- find prime factors of 24, 36, 48 .
e.g. Prime factors of 24 = 1× 2 × 2 × 2 × 3
Prime factors of 36 = 1 × 2 × 2 × 3 × 3
Prime factors of 48 = 1 × 2 × 2 × 2 × 2 × 3

Step2 :- find common factors .
e.g. Common factors = 1 × 2 × 2 × 3 = 12

we know, HCF is the highest common factors
Or HCF { 24, 36, 48} = common factors{24, 36, 48} = 12

Hence, HCF of 24, 36, 48 = 12
