Given numbers has no common factors except 1. So, there LCD is their product i.e 363362370

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(785, 721) = 1

LCD(785, 721) = ( 785 x 721 ) / 1

LCD(785, 721) = 565985 / 1

LCD(785, 721) = 565985

Step2:

Here we consider the LCD from the above i.e. 565985 as first number and the next as 642

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

GCF(565985, 642) = 1

LCD(565985, 642) = ( 565985 x 642 ) / 1

LCD(565985, 642) = 363362370 / 1

LCD(565985, 642) = 363362370

LCD of 785,721,642 is 363362370
