Given numbers has no common factors except 1. So, there LCD is their product i.e 181865264

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(551, 784) = 1

LCD(551, 784) = ( 551 x 784 ) / 1

LCD(551, 784) = 431984 / 1

LCD(551, 784) = 431984

Step2:

Here we consider the LCD from the above i.e. 431984 as first number and the next as 421

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

GCF(431984, 421) = 1

LCD(431984, 421) = ( 431984 x 421 ) / 1

LCD(431984, 421) = 181865264 / 1

LCD(431984, 421) = 181865264

LCD of 551,784,421 is 181865264
