LCD of 644, 717, 605 Calculator

Arrange the Inputs 644,717,605 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 279357540

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(644, 717) = 1

LCD(644, 717) = ( 644 x 717 ) / 1

LCD(644, 717) = 461748 / 1

LCD(644, 717) = 461748

Step2:

Here we consider the LCD from the above i.e. 461748 as first number and the next as 605

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

GCF(461748, 605) = 1

LCD(461748, 605) = ( 461748 x 605 ) / 1

LCD(461748, 605) = 279357540 / 1

LCD(461748, 605) = 279357540

LCD of 644,717,605 is 279357540
