Answer:
42
Step-by-step explanation:
Start with the higher denominator, that is 14
Divide 14 by 6 and if the remainder is zero then 14 is the LCD
If not repeat the process with multiples of 14
14 ÷ 6 = 2 remainder 2 ← not 14, Try 28
28 ÷ 6 = 4 remainder 4 ← not 28, Try 42
42 ÷ 6 = 7 remainder 0 ← 42 is the LCD
