1. The smallest square number divisible by 10, 16 and 24 is ?
= 5 × 2 × 8 × 3 = 240
⇒ for square number split the LCM into its factors
= 5 × 2 × 2 × 2 × 2 × 3
= 5 × 5 × 2 × 2 × 2 × 2 × 3 × 3
= 3600
Solution:
LCM (10, 16, 24)= 5 × 2 × 8 × 3 = 240
⇒ for square number split the LCM into its factors
= 5 × 2 × 2 × 2 × 2 × 3
= 5 × 5 × 2 × 2 × 2 × 2 × 3 × 3
= 3600
