2.2. Write down: 2.2.1. the prime factors of 132 . 2.2 .2 . the HCF of 48 and 88 . 2.2 .3 . the LCM of 24 and 96 .

2.2.1. Prime factors of 132:   132 can be broken down as follows:   132 = 2 × 66     = 2 × 2 × 33     = 2 × 2 × 3 × 11   Thus, the prime factors are 2, 2, 3, and 11 (or simply 2, 3, and 11 as the unique prime factors). 2.2.2. HCF (Highest Common Factor) of 48 and 88:   First, express each number in its prime factorization:   48 = 2⁴ × 3   88 = 2³ × 11   The common prime factors are with base 2. Take the smallest exponent:   HCF = 2³ = 8. 2.2.3. LCM (Least Common Multiple) of 24 and 96:   Write the factorizations:   24 = 2³ × 3   96 = 2⁵ × 3   For LCM, take the highest powers of all primes present:   LCM = 2⁵ × 3 = 32 × 3 = 96. Thus, the answers are:  • Prime factors of 132: 2, 2, 3, 11 (or 2, 3, and 11).  • HCF of 48 and 88: 8.  • LCM of 24 and 96: 96.
