HCF means highest common multiple
To find the HCF of 120 and 128, we have factorize them individually and write them in the product of prime numbers.
120=(2^3)×3×5
168=(2^3)×3×7
The common multiple between 120 and 168 is (2^3)×3
(2^3)×3=8×3=24
Therefore the HCF of 120 and 168 is 24.

Solution:
Prime factors of 120 = 2*2*2*3*5
Prime factors of 168 = 2*2*2*3*7
Common Factors = 2*2*2*3
So, H.C.F. of 120 and 168 = 2*2*2*3
= 24
