LCD of 85, 212, 721 Calculator

Arrange the Inputs 85,212,721 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 12992420

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(85, 212) = 1

LCD(85, 212) = ( 85 x 212 ) / 1

LCD(85, 212) = 18020 / 1

LCD(85, 212) = 18020

Step2:

Here we consider the LCD from the above i.e. 18020 as first number and the next as 721

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

GCF(18020, 721) = 1

LCD(18020, 721) = ( 18020 x 721 ) / 1

LCD(18020, 721) = 12992420 / 1

LCD(18020, 721) = 12992420

LCD of 85,212,721 is 12992420
