Given Input Data is 655, 585, 181, 977

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

Prime Factorization of 655 is 5 x 131

Prime Factorization of 585 is 3 x 3 x 5 x 13

Prime Factorization of 181 is 181

Prime Factorization of 977 is 977

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(655, 585) = 76635

GCD(655, 585) = ( 655 x 585 ) / 76635

GCD(655, 585) = 383175 / 76635

GCD(655, 585) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 181

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

LCM(5, 181) = 905

GCD(5, 181) = ( 5 x 181 ) / 905

GCD(5, 181) = 905 / 905

GCD(5, 181) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 977

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

LCM(1, 977) = 977

GCD(1, 977) = ( 1 x 977 ) / 977

GCD(1, 977) = 977 / 977

GCD(1, 977) = 1

GCD of 655, 585, 181, 977 is 1
