The least common denominator is 14.
Whenever there are two values, and one is a multiple of the other, the multiple (larger number) is the LCD.
14
It is: 28
42
It is: 70
49 x 2 = 98 14 x 7 = 98 98 is the LCD
The LCD for 2 and 7 is 14
28
It would be 14. 7 x 2 = 14. 2 is the smallest integer you can multiply 7 by to get a number that is factorable by 2.
It is: 294 which is the same as its LCM
20
The least common denominator (LCD) is 1.
LCD(5, 14) = 70
