    Why not just multiply 14 × 21 × 35?

  • 1,050 ÷ 14 = 75 ✓
    1,050 is a four-digit number
    3. Use division + ceiling of the smallest four-digit number (1,000) by the LCM to find the first multiple.

    To solve the question, begin with understanding divisibility. Four-digit numbers range from 1,000 to 9,999. The key is finding the smallest number in this range divisible by 14, 21, and 35. These numbers share common factors: 14 = 2 × 7, 21 = 3 × 7, and 35 = 5 × 7. Their least common multiple (LCM) combines each prime factor at its highest power: 2 × 3 × 5 × 7 = 210. Thus, any number divisible by all three must be a multiple of 210. The smallest four-digit multiple of 210 is what we seek.

  • Curious individuals exploring logic puzzles and cognitive training
  • Encouraging Further Exploration

  • Yes—in for four-digit limits, testing multiples of 210 starting at 5 is efficient and ensures accuracy.
