q001:

They both have same greatest common divisor. We add the two prime factorizations together to get 420, which is the least common multiple

q002:

84=2*2*3*7 and 126=2*3*3*7 and the greatest common divisor would be 2*3*7=42 while the least common multiple would be 2*2*3*3*7=252

q003:

First you would have to find the prime factorizations of both numbers. 504=2*2*2*3*3*7 and 378=2*3*3*3*7. The greatest common divisor

2*3*3*7=126 and the least common multiple is 2*2*2*3*3*3*7=1512.
