If that's 5/12, 10/13 and 7/9, the LCD is 468.
LCD(40, 50) = 200
Write the multiples of each: 5, 10, 15, 20 10, 20, 30, 40 10 is in each, so it is the answer.
20
The LCD of 5 and 4 is 20.
The least common multiple of 13 and 20 is 260.
20
260
LCD(10, 20) = 20

Lcd of 5,4,2 is 20 because 5*4=20 and 2*10=20
20
240
LCD(40, 50) = 200
Pairs of number with the LCD of 5 are 5 and 10, 10 and 15, 20 and 25, and many more.
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.
Write the multiples of each: 5, 10, 15, 20 10, 20, 30, 40 10 is in each, so it is the answer.
