Given numbers has no common factors except 1. So, there LCD is their product i.e 175687512

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, 312) = 1

LCD(781, 312) = ( 781 x 312 ) / 1

LCD(781, 312) = 243672 / 1

LCD(781, 312) = 243672

Step2:

Here we consider the LCD from the above i.e. 243672 as first number and the next as 721

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

GCF(243672, 721) = 1

LCD(243672, 721) = ( 243672 x 721 ) / 1

LCD(243672, 721) = 175687512 / 1

LCD(243672, 721) = 175687512

LCD of 781,312,721 is 175687512
