Question

find the hcf of 144 and 120 ​

Answer 1

Answer:

HCF(120,144)=24,

LCM(120,144)=720.

Every composite number can be expressed as a product of primes, and this factorisation is unique, apart from the order in which the prime factors occur.

120 = 2³×3¹×5¹

144 = 2⁴×3²

HCF(120,144)=2³×3¹ = 8×3=24.

LCM(120,144)=2⁴×3²×5¹

= 720.
