Given numbers has no common factors except 1. So, there LCD is their product i.e 397821710

Step1:

Let's calculate the LCD of first two numbers

The formula of LCD is LCD(a,b) = ( a x b) / GCF(a,b)

GCF(638, 905) = 1

LCD(638, 905) = ( 638 x 905 ) / 1

LCD(638, 905) = 577390 / 1

LCD(638, 905) = 577390

Step2:

Here we consider the LCD from the above i.e. 577390 as first number and the next as 689

The formula of LCD is LCD(a,b) = ( a x b) / GCF(a,b)

GCF(577390, 689) = 1

LCD(577390, 689) = ( 577390 x 689 ) / 1

LCD(577390, 689) = 397821710 / 1

LCD(577390, 689) = 397821710

LCD of 638,905,689 is 397821710
