If a … NettetThis video provides an example of determining the least common multiple of two numbers by using prime factorization.Complete video list at http://www.mathisp... Nettet19. des. 2024 · Second method: Factor the two numbers into products of powers of prime numbers. Create a new number multiplying together all the primes occurring in either number, raised to the higher of the two exponents. That is the LCM. Example: LCM of 45 and 12. 45 = 3^2*5, 12 = 2^2*3. New number = 2^2*3^2*5 = 180, the LCM sought. paesaggio valle d\\u0027aosta
