Given numbers has no common factors except 1. So, there LCD is their product i.e 572247291

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(861, 851) = 1

LCD(861, 851) = ( 861 x 851 ) / 1

LCD(861, 851) = 732711 / 1

LCD(861, 851) = 732711

Step2:

Here we consider the LCD from the above i.e. 732711 as first number and the next as 781

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

GCF(732711, 781) = 1

LCD(732711, 781) = ( 732711 x 781 ) / 1

LCD(732711, 781) = 572247291 / 1

LCD(732711, 781) = 572247291

LCD of 861,851,781 is 572247291
