To find the LCD & HCF we have to find the prime factors of the numbers
195 = 3 × 85
= 3 × 5 × 17
225 = 3 × 75
= 3 × 3 × 25
= 3 × 3 × 5 × 5
LCM = 3 × 5
= 15
HCF = 3 × 3 × 5 × 5 × 17
= 225 × 17
= 3825
So LCM = 3825
HCF = 15
195 = 3 × 85
= 3 × 5 × 17
225 = 3 × 75
= 3 × 3 × 25
= 3 × 3 × 5 × 5
LCM = 3 × 5
= 15
HCF = 3 × 3 × 5 × 5 × 17
= 225 × 17
= 3825
So LCM = 3825
HCF = 15
