LCD of 77, 69, 85 Calculator

Arrange the Inputs 77,69,85 in a horizontal line separated by commas and divide them with a prime number. Note the quotients in the next row and divide with quotients with prime numbers again. Continue the process until you have all co primes in the last.

Given numbers has no common factors except 1. So, there LCD is their product i.e 451605

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(77, 69) = 1

LCD(77, 69) = ( 77 x 69 ) / 1

LCD(77, 69) = 5313 / 1

LCD(77, 69) = 5313

Step2:

Here we consider the LCD from the above i.e. 5313 as first number and the next as 85

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

GCF(5313, 85) = 1

LCD(5313, 85) = ( 5313 x 85 ) / 1

LCD(5313, 85) = 451605 / 1

LCD(5313, 85) = 451605

LCD of 77,69,85 is 451605
