Given numbers has no common factors except 1. So, there LCD is their product i.e 279822928

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(457, 781) = 1

LCD(457, 781) = ( 457 x 781 ) / 1

LCD(457, 781) = 356917 / 1

LCD(457, 781) = 356917

Step2:

Here we consider the LCD from the above i.e. 356917 as first number and the next as 784

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

GCF(356917, 784) = 1

LCD(356917, 784) = ( 356917 x 784 ) / 1

LCD(356917, 784) = 279822928 / 1

LCD(356917, 784) = 279822928

LCD of 457,781,784 is 279822928
