Find HCF and LCM of 6,72,120give fast

Answer»

The answer is given below :

The given numbers are 6, 72 and 120.

By prime factorization method, we find

6 = 2 × 3

72 = 2 × 2 × 2 × 3 × 3

120 = 2 × 2 × 2 × 3 × 5

HCF = HIGHEST COMMON FACTOR,
i.e., the common FACTORS of all the THREE numbers

So, required HCF

= 2 × 3

= 6

LCM = LEAST COMMON MULTIPLE,
i.e., the number multipled by all the three numbers

So, required LCM

= 2 × 3 × 2 × 2 × 3 × 5

= 360

Thank you for your question.
