Answer:
4·6 = 24 ≠ 12 = LCM(4, 6)
Step-by-step explanation:
Any pair of numbers with a common factor will refute Sarah's conjecture.
One such pair is 4 and 6, which have a product of 24. The LCM of 4 and 6 is 12, which is that product divided by their common factor of 2.

Answer:
A and C
Step-by-step explanation:
A) 160 + 20 = 180
B) 120 + 40 = 160
C) 45 + 135 = 180
D) 30 + 120 = 150
