Best ResponseYou've already chosen the best response.3When asked to find GCD and LCM. I create the set of prime factors of the number, but i dont use exponents. I leave them as sets of primes 12: {2,2,3} 45: {3,3,5} I then line up the sets like this 12: {2,2,3 } 45: { 3,3,5 } placing like values in columns, and any extra iterations are just left hanging the GCD is what they have in common, the intersection of the two sets 12: {2,2,3 } 45: { 3,3,5 }  GCD: { 3 } ; multiply the set altogheter, in thats case its just 3 the LCM is what they have joined together, the union of the two sets 12: {2,2,3 } 45: { 3,3,5 }  LCM:{2,2,3,3,5} ; multiply the set altogether

Best ResponseYou've already chosen the best response.3class today was trying to go thru "rules" such that: the greatest common divisor uses the smallest exponent; and the least common multiple uses the biggest exponents; and quite frankly; i find that rather confusing to keep track of
