Therefore, GCD of numbers 620, 550, 79, 573 is 1

Given Input Data is 620, 550, 79, 573

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 550 is 2 x 5 x 5 x 11

Prime Factorization of 79 is 79

Prime Factorization of 573 is 3 x 191

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, 550) = 34100

GCD(620, 550) = ( 620 x 550 ) / 34100

GCD(620, 550) = 341000 / 34100

GCD(620, 550) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 79

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

LCM(10, 79) = 790

GCD(10, 79) = ( 10 x 79 ) / 790

GCD(10, 79) = 790 / 790

GCD(10, 79) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 573

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

LCM(1, 573) = 573

GCD(1, 573) = ( 1 x 573 ) / 573

GCD(1, 573) = 573 / 573

GCD(1, 573) = 1

GCD of 620, 550, 79, 573 is 1
