Given numbers has no common factors except 1. So, there LCD is their product i.e 427467201

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(687, 863) = 1

LCD(687, 863) = ( 687 x 863 ) / 1

LCD(687, 863) = 592881 / 1

LCD(687, 863) = 592881

Step2:

Here we consider the LCD from the above i.e. 592881 as first number and the next as 721

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

GCF(592881, 721) = 1

LCD(592881, 721) = ( 592881 x 721 ) / 1

LCD(592881, 721) = 427467201 / 1

LCD(592881, 721) = 427467201

LCD of 687,863,721 is 427467201
