Therefore, GCD of numbers 239, 285, 69, 691 is 1

Given Input Data is 239, 285, 69, 691

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

Prime Factorization of 239 is 239

Prime Factorization of 285 is 3 x 5 x 19

Prime Factorization of 69 is 3 x 23

Prime Factorization of 691 is 691

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(239, 285) = 68115

GCD(239, 285) = ( 239 x 285 ) / 68115

GCD(239, 285) = 68115 / 68115

GCD(239, 285) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 69

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

LCM(1, 69) = 69

GCD(1, 69) = ( 1 x 69 ) / 69

GCD(1, 69) = 69 / 69

GCD(1, 69) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 691

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

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

GCD(1, 691) = 691 / 691

GCD(1, 691) = 1

GCD of 239, 285, 69, 691 is 1
