Therefore, GCD of numbers 620, 210, 53, 679 is 1

Given Input Data is 620, 210, 53, 679

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

Prime Factorization of 620 is 2 x 2 x 5 x 31

Prime Factorization of 210 is 2 x 3 x 5 x 7

Prime Factorization of 53 is 53

Prime Factorization of 679 is 7 x 97

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(620, 210) = 13020

GCD(620, 210) = ( 620 x 210 ) / 13020

GCD(620, 210) = 130200 / 13020

GCD(620, 210) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 53

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

LCM(10, 53) = 530

GCD(10, 53) = ( 10 x 53 ) / 530

GCD(10, 53) = 530 / 530

GCD(10, 53) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 679

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

LCM(1, 679) = 679

GCD(1, 679) = ( 1 x 679 ) / 679

GCD(1, 679) = 679 / 679

GCD(1, 679) = 1

GCD of 620, 210, 53, 679 is 1
