I am assuming that 4, 2, and 6 are the denominators of some fractions. That being said. LCD means Least Common Multiple of the Denominators.
So you need to find the Least Common multiple of the Denominators 4, 2, and 6. This means the smallest multiple they have in common.
The multiples of each number are listed below: Remember multiples keep going on forever so I'm only listing the first few.
4: 4, 8, 12, 16, 20, 24, 28, 32...
2: 2, 4, 6, 8, 10, 12, 14, 16...
6: 6, 12, 18, 24, 60, 36, 42, 48...
Notice that the smallest multiple they have in common is 12. They have other multiples in common like 24, but it isn't the smallest.
The LCD of 4, 2, and 6 = 12.
2
lcd(6, 12, 16) = 48. 6 = 2 x 3 12 = 2^2 x 3 16 = 2^4 lcd = 2^4 x 3 = 48
the answer is 60
24
The LCD of 11/6 and 2/4 is 12.
lcd(2, 6, 12) = 12.
LCD(2, 3) = 6.
LCD(4, 2, 9) = 36
The LCD of 2/3, 5/6, and 3/4 is 24
The LCD of 1/4 and 1/6 is 12
th less common denominator for 2 5 4 3 is 6
2/12=1/6 The LCD of 1/6 and 3/4=The LCD of 1/6 and 1/4=12 Therefore, 2/12 and 9/12 have the same denominator. They are equal to the original fractions. LCD=12
LCD(2, 3, 4, 6, 8, 10) = 120
