Answer:
To find the HCF of 4 and 6, we will find the prime factorization of the given numbers, i.e. 4 = 2 × 2; 6 = 2 × 3. ⇒ Since 2 is the only common prime factor of 4 and 6. Hence, HCF (4, 6) = 2.
The LCM of 4 and 6 is 12. To find the least common multiple (LCM) of 4 and 6, we need to find the multiples of 4 and 6 (multiples of 4 = 4, 8, 12, 16; multiples of 6 = 6, 12, 18, 24) and choose the smallest multiple that is exactly divisible by 4 and 6, = 12.
