Prime Factorization Method

There are multiple ways to find the least common multiple of given integers. In this method, we find the prime factors of each number, and then take the highest power of each prime that appears in the factorization of either number for find LCM.

  • Find the prime factorization of each number:

806 = 2, 13, 31

1747 = 1747

  • Identify the highest powers of all prime numbers that appear in the factorization: 21×131×311×174712^1 × 13^1 × 31^1 × 1747^1
  • To find LCM multiply these highest powers: LCM(806, 1747) = 21×131×311×174712^1 × 13^1 × 31^1 × 1747^1 = 1408082
