WebbThe lcm will be the product of multiplying the highest power of each prime number together. The highest power of the three prime numbers 2, 3, and 7 is 2 3, 3 2, and 7 1, respectively. Thus, This method is not as efficient as reducing to the greatest common divisor, since there is no known general efficient algorithm for integer factorization . WebbThis 12 is the least common multiple (LCM) of 3 and 4. The same thing happened in our problem. To find the year both events occur again, we have to find the LCM of 7 and 6. LCM (7, 6) = 42 years. If both events occur in 2008, again they occur after 42 years. = 2008 + 42 = 2050. In 2050 both events will occur again. 5. Answer :
