Therefore, GCD of numbers 260, 380, 23, 621 is 1

Given Input Data is 260, 380, 23, 621

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

Prime Factorization of 260 is 2 x 2 x 5 x 13

Prime Factorization of 380 is 2 x 2 x 5 x 19

Prime Factorization of 23 is 23

Prime Factorization of 621 is 3 x 3 x 3 x 23

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(260, 380) = 4940

GCD(260, 380) = ( 260 x 380 ) / 4940

GCD(260, 380) = 98800 / 4940

GCD(260, 380) = 20

Step2:

Here we consider the GCD from the above i.e. 20 as first number and the next as 23

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

LCM(20, 23) = 460

GCD(20, 23) = ( 20 x 23 ) / 460

GCD(20, 23) = 460 / 460

GCD(20, 23) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 621

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

LCM(1, 621) = 621

GCD(1, 621) = ( 1 x 621 ) / 621

GCD(1, 621) = 621 / 621

GCD(1, 621) = 1

GCD of 260, 380, 23, 621 is 1
