Therefore, GCD of numbers 656, 246, 73, 203 is 1

Given Input Data is 656, 246, 73, 203

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

Prime Factorization of 656 is 2 x 2 x 2 x 2 x 41

Prime Factorization of 246 is 2 x 3 x 41

Prime Factorization of 73 is 73

Prime Factorization of 203 is 7 x 29

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(656, 246) = 1968

GCD(656, 246) = ( 656 x 246 ) / 1968

GCD(656, 246) = 161376 / 1968

GCD(656, 246) = 82

Step2:

Here we consider the GCD from the above i.e. 82 as first number and the next as 73

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

LCM(82, 73) = 5986

GCD(82, 73) = ( 82 x 73 ) / 5986

GCD(82, 73) = 5986 / 5986

GCD(82, 73) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 203

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

LCM(1, 203) = 203

GCD(1, 203) = ( 1 x 203 ) / 203

GCD(1, 203) = 203 / 203

GCD(1, 203) = 1

GCD of 656, 246, 73, 203 is 1
