The GCF is 5.
Lcd of 5,4,2 is 20 because 5*4=20 and 2*10=20

LCD(40, 50) = 200
The LCD is 60. (60/4 = 15, 60/5 = 12, 60/6 = 10)
It is: 40 which is also the LCM
To find the least common denominator (LCD) of one quarter (1/4) and three tenths (3/10), first determine the denominators, which are 4 and 10. The multiples of 4 are 4, 8, 12, 16, 20, and the multiples of 10 are 10, 20, 30. The smallest common multiple of both numbers is 20, so the LCD is 20.
