Given numbers has no common factors except 1. So, there LCD is their product i.e 137733354

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(747, 638) = 1

LCD(747, 638) = ( 747 x 638 ) / 1

LCD(747, 638) = 476586 / 1

LCD(747, 638) = 476586

Step2:

Here we consider the LCD from the above i.e. 476586 as first number and the next as 289

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

GCF(476586, 289) = 1

LCD(476586, 289) = ( 476586 x 289 ) / 1

LCD(476586, 289) = 137733354 / 1

LCD(476586, 289) = 137733354

LCD of 747,638,289 is 137733354
