Given numbers has no common factors except 1. So, there LCD is their product i.e 437615828

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(641, 691) = 1

LCD(641, 691) = ( 641 x 691 ) / 1

LCD(641, 691) = 442931 / 1

LCD(641, 691) = 442931

Step2:

Here we consider the LCD from the above i.e. 442931 as first number and the next as 988

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

GCF(442931, 988) = 1

LCD(442931, 988) = ( 442931 x 988 ) / 1

LCD(442931, 988) = 437615828 / 1

LCD(442931, 988) = 437615828

LCD of 641,691,988 is 437615828
