Given numbers has no common factors except 1. So, there LCD is their product i.e 209681997

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(777, 421) = 1

LCD(777, 421) = ( 777 x 421 ) / 1

LCD(777, 421) = 327117 / 1

LCD(777, 421) = 327117

Step2:

Here we consider the LCD from the above i.e. 327117 as first number and the next as 641

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

GCF(327117, 641) = 1

LCD(327117, 641) = ( 327117 x 641 ) / 1

LCD(327117, 641) = 209681997 / 1

LCD(327117, 641) = 209681997

LCD of 777,421,641 is 209681997
