Key Insights
To find the smallest three-digit number divisible by both 15 and 18, start by determining the least common multiple (LCM). These two numbers share prime factors: 15 = 3 × 5, 18 = 2 × 3². The LCM takes the highest power of each prime:
2¹ × 3² × 5¹ = 2 × 9 × 5 = 90.
Now, find the smallest three-digit multiple of 90. Divide 100 by 90:
100 ÷ 90 ≈ 1.11 → round up to 2.
Now multiply: 90 × 2 = 180.
So, 180 is the smallest three-digit number divisible by both 15 and 18.
