Answer: 900 Step-by-step explanation: Since, we wanted smallest perfect square number divisible by 6, 9 and 15. So, we calculated LCM by prime factorisation. LCM = 90 But, 2 and 5 are not in pair. Therefore, to make it perfect square no. multiply 2 × 5 to LCM (90). = 90 × 2 × 5 = 90 × 10 = 900 Hence, Required smallest square no. that’s divisible by 6, 9 and 15 = 900 Reply
Answer:
900
Step-by-step explanation:
Since, we wanted smallest perfect square number divisible by 6, 9 and 15.
So, we calculated LCM by prime factorisation.
LCM = 90
But, 2 and 5 are not in pair.
Therefore, to make it perfect square no. multiply 2 × 5 to LCM (90).
= 90 × 2 × 5
= 90 × 10
= 900
Hence,
Required smallest square no. that’s divisible by 6, 9 and 15 = 900
