Answer 2

$\huge \red{{a.} \: 50 \: and \: 75}$

Prime factorization of 50 is

2 × 5 × 5

Prime factorization of 75 is

3 × 5 × 5

Common factors = 5, 5

HCF is 5 × 5 = 25

LCM is 2 × 3 × 5 × 5 = 150

$\huge \red{b. \: 110 \: and \: 115}$

Prime factorization of 110 is

110 = 2 × 5 × 11

Prime factorization of 115 is

115 = 5 × 23

Common factors = 5

HCF = 5

LCM = 2 × 5 × 11 × 23 = 2530
