Given numbers has no common factors except 1. So, there LCD is their product i.e 286536389

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(421, 829) = 1

LCD(421, 829) = ( 421 x 829 ) / 1

LCD(421, 829) = 349009 / 1

LCD(421, 829) = 349009

Step2:

Here we consider the LCD from the above i.e. 349009 as first number and the next as 821

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

GCF(349009, 821) = 1

LCD(349009, 821) = ( 349009 x 821 ) / 1

LCD(349009, 821) = 286536389 / 1

LCD(349009, 821) = 286536389

LCD of 421,829,821 is 286536389
