Given Input Data is 965, 155, 355, 443

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

Prime Factorization of 965 is 5 x 193

Prime Factorization of 155 is 5 x 31

Prime Factorization of 355 is 5 x 71

Prime Factorization of 443 is 443

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(965, 155) = 29915

GCD(965, 155) = ( 965 x 155 ) / 29915

GCD(965, 155) = 149575 / 29915

GCD(965, 155) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 355

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

LCM(5, 355) = 355

GCD(5, 355) = ( 5 x 355 ) / 355

GCD(5, 355) = 1775 / 355

GCD(5, 355) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 443

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

LCM(5, 443) = 2215

GCD(5, 443) = ( 5 x 443 ) / 2215

GCD(5, 443) = 2215 / 2215

GCD(5, 443) = 1

GCD of 965, 155, 355, 443 is 1
