Answer 1

• Answer:

900

• Step-by-step explanation:

6 = 2×3

9 = 3²

15 = 3×5

lcm = 2×3²×5 = 90

to have a square number multiple of 90 we have to multiply by 2 and 5

2×3²×5 × 2×5 = 2²×3²×5² = (2×3×5)² = 30² = 900

Good luck !

Answer 2

Answer:

$\frac{6}{3} = 2$

$\frac{9}{3} = 3$

$\frac{15}{3} = 5$

So the smallest number is 3. As it divides 6,9 and 15.
