Given numbers has no common factors except 1. So, there LCD is their product i.e 361039899

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(781, 669) = 1

LCD(781, 669) = ( 781 x 669 ) / 1

LCD(781, 669) = 522489 / 1

LCD(781, 669) = 522489

Step2:

Here we consider the LCD from the above i.e. 522489 as first number and the next as 691

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

GCF(522489, 691) = 1

LCD(522489, 691) = ( 522489 x 691 ) / 1

LCD(522489, 691) = 361039899 / 1

LCD(522489, 691) = 361039899

LCD of 781,669,691 is 361039899
