LCD of 80, 109, 687 Calculator

Arrange the Inputs 80,109,687 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 5990640

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(80, 109) = 1

LCD(80, 109) = ( 80 x 109 ) / 1

LCD(80, 109) = 8720 / 1

LCD(80, 109) = 8720

Step2:

Here we consider the LCD from the above i.e. 8720 as first number and the next as 687

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

GCF(8720, 687) = 1

LCD(8720, 687) = ( 8720 x 687 ) / 1

LCD(8720, 687) = 5990640 / 1

LCD(8720, 687) = 5990640

LCD of 80,109,687 is 5990640
