th less common denominator for 2 5 4 3 is 6
The LCD is 60. (60/4 = 15, 60/5 = 12, 60/6 = 10)
This can be done in an equation only. Multiply the entire equation by the LCD. This cancels every denominator leaving an equation with no fractions. EX: x/3 + 2/5 = 3/4 so the LCD for 3,5, and 4 is 60 60(x/3) + 60(2/5) = 60(3/4) 20(x) + 12(2) = 15(3) no more fractions, just solve.
The multiples of 10 are: 1, 2, 5, 10 The multiples of 5 are: 1 and 5. The multiples of 6 are: 1, 2, 3, and 6. The multiples of 8 are: 1, 2, 4, and 8. The number that they all have in common is 1, so the lcd is one.
LCD(3, 5, 4, 2) = 60

The LCD of 5 and 4 is 20.
the answer is 60
th less common denominator for 2 5 4 3 is 6
28.
the LCD of 2, 9 and 5 = 90
LCD(5, 4, 10, 3) = 60
If that's 84 and 35, the LCD is 420.If that's 8/4 and 3/5, the LCD is 20.
LCD(4, 2, 9) = 36
