find LCM and HCF of following
i. 25,75,100 ii. 800,64,192
Answers
Answer:
- 25 = 5 × 5
75 = 3 × 5 × 5
100 = 2 × 2 × 5 × 5
From above factors we found that HCF( 25 , 75 , 100 ) = 5 × 5 = 25
LCM ( 25 , 75 , 100 ) = 25 × 3 × 2 × 2
= 300
2. 800 = 2³ × 2² × 5²
64 = 2³ × 2² × 2
192 = 2³ × 2² × 2 × 3
From above factors we found that, HCF( 800 , 64 , 192 ) = 2³ × 2² = 32
LCM( 800 , 64 , 192 ) = 32 × 5² × 2 ×
2 × 3 = 9600
