Question

Find the least number which is a perfect square and exactly divisible
by 10,12 and 15​

Answer 1

Answer:

• 900

Step-by-step explanation:

Factorize each number and find the smallest number that is a product of double of each factor:

• 10 = 2*5
• 12 = 2*2*3
• 15 = 3*5

We need the number:

• 2*2*3*3*5*5 = (2*3*5)² = 30² = 900
