It's easier to see with prime factorizations. Consider 30 and 42. 2 x 3 x 5 = 30 2 x 3 x 7 = 42 Their product is (2 x 3 x 5)(2 x 3 x 7) = 1260 Their GCF is 2 x 3 Their LCM is 2 x 3 x 5 x 7 That product is (2 x 3)(2 x 3 x 5 x 7) = 1260 Consider two prime numbers, 5 and 7. Their product is 35. Their GCF is 1. Their LCM is 35. That product is also 35.
