Therefore, GCD of numbers 243, 414, 856, 694 is 1

Given Input Data is 243, 414, 856, 694

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 243 is 3 x 3 x 3 x 3 x 3

Prime Factorization of 414 is 2 x 3 x 3 x 23

Prime Factorization of 856 is 2 x 2 x 2 x 107

Prime Factorization of 694 is 2 x 347

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(243, 414) = 11178

GCD(243, 414) = ( 243 x 414 ) / 11178

GCD(243, 414) = 100602 / 11178

GCD(243, 414) = 9

Step2:

Here we consider the GCD from the above i.e. 9 as first number and the next as 856

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(9, 856) = 7704

GCD(9, 856) = ( 9 x 856 ) / 7704

GCD(9, 856) = 7704 / 7704

GCD(9, 856) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 694

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 694) = 694

GCD(1, 694) = ( 1 x 694 ) / 694

GCD(1, 694) = 694 / 694

GCD(1, 694) = 1

GCD of 243, 414, 856, 694 is 1
