Therefore, GCD of numbers 193, 451, 73, 688 is 1

Given Input Data is 193, 451, 73, 688

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

Prime Factorization of 193 is 193

Prime Factorization of 451 is 11 x 41

Prime Factorization of 73 is 73

Prime Factorization of 688 is 2 x 2 x 2 x 2 x 43

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(193, 451) = 87043

GCD(193, 451) = ( 193 x 451 ) / 87043

GCD(193, 451) = 87043 / 87043

GCD(193, 451) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 73

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

LCM(1, 73) = 73

GCD(1, 73) = ( 1 x 73 ) / 73

GCD(1, 73) = 73 / 73

GCD(1, 73) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 688

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

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

GCD(1, 688) = 688 / 688

GCD(1, 688) = 1

GCD of 193, 451, 73, 688 is 1
