Finding LCD of 87,40,89 using GCF Formula

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(87, 40) = 1

LCD(87, 40) = ( 87 x 40 ) / 1

LCD(87, 40) = 3480 / 1

LCD(87, 40) = 3480


Step2:

Here we consider the LCD from the above i.e. 3480 as first number and the next as 89

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

GCF(3480, 89) = 1

LCD(3480, 89) = ( 3480 x 89 ) / 1

LCD(3480, 89) = 309720 / 1

LCD(3480, 89) = 309720

LCD of 87,40,89 is 309720
