Given numbers has no common factors except 1. So, there LCD is their product i.e 129869610

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(689, 206) = 1

LCD(689, 206) = ( 689 x 206 ) / 1

LCD(689, 206) = 141934 / 1

LCD(689, 206) = 141934

Step2:

Here we consider the LCD from the above i.e. 141934 as first number and the next as 915

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

GCF(141934, 915) = 1

LCD(141934, 915) = ( 141934 x 915 ) / 1

LCD(141934, 915) = 129869610 / 1

LCD(141934, 915) = 129869610

LCD of 689,206,915 is 129869610
