Question

the ratio of LCM and HCF of the least composite and the least add prime numbers
a)1:12
b)12:1
c)1:1
d)1:3​

Answer 1

Answer:

2:1

Step-by-step explanation:

Required ratio of LCM : HCF = 4 : 2 = 2 : 1 (b) (Ans.) Hence, the ratio of LCM and HCF of the least composite and the least prime numbers is 2 : 1 .

Answer 2

Answer:

● Least composite number = 4

● Least odd prime number = 2

So, prime factors of 4 and 3 are

• 4 = 2 × 2

• 2 = 1 × 2

Then,

LCM = 2 × 2 = 4

HCF = 2

Therefore,

Required ratio of LCM : HCF = 4 : 2 = 2 : 1

Hence, the answer is 2 : 1.
