LCD(7, 5, 10) = 10
90
LCD (Least Common Divisor) is not a normal term. LCM (Least Common Multiple) is, as well as GCD (Greatest Common Divisor). The LCM of 10 and 25 is 50, while the GCD of 10 and 50 is 10. I suppose if you were really looking for the LCD of 10 and 25, it is 5.
Only if the LCD is different from the others. If you were adding 1/5 to 1/10, you wouldn't have to change the numerator of 1/10 since 10 is the LCD. But if you're adding 1/5 + 1/7, you have to change both numerators since the LCD in that case is 35.
If that's 84 and 35, the LCD is 420.If that's 8/4 and 3/5, the LCD is 20.
LCD(7, 5, 10) = 10
LCD(5, 4, 10, 3) = 60

Pairs of number with the LCD of 5 are 5 and 10, 10 and 15, 20 and 25, and many more.

The LCD or least common multiple of the numbers 5 and 2 is 10.
Lcd of 5,4,2 is 20 because 5*4=20 and 2*10=20
The LCD for the two numbers is 10
