Given Input Data is 722, 858, 543, 191

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

Prime Factorization of 722 is 2 x 19 x 19

Prime Factorization of 858 is 2 x 3 x 11 x 13

Prime Factorization of 543 is 3 x 181

Prime Factorization of 191 is 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(722, 858) = 309738

GCD(722, 858) = ( 722 x 858 ) / 309738

GCD(722, 858) = 619476 / 309738

GCD(722, 858) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 543

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

LCM(2, 543) = 1086

GCD(2, 543) = ( 2 x 543 ) / 1086

GCD(2, 543) = 1086 / 1086

GCD(2, 543) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 191

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

LCM(1, 191) = 191

GCD(1, 191) = ( 1 x 191 ) / 191

GCD(1, 191) = 191 / 191

GCD(1, 191) = 1

GCD of 722, 858, 543, 191 is 1
