Answer 2

first write the prime factors of 18, 16 and 32

18= 2×3×3

16= 2×2×2×2

32= 2×2×2×2×2

now we can write,

18= 2¹×3²

16= 2⁴

32= 2⁵

here, 2¹ is the smallest power common prime factor 2.

So, HCF (18,16,32) = 2

2⁵and 3² are the greatest power of prime factors 2 and 3 respectively involved in three numbers.

So, LCM (18,16,32) = 2⁵× 3² = 288
