Given Input Data is 270, 104, 26, 661

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

Prime Factorization of 270 is 2 x 3 x 3 x 3 x 5

Prime Factorization of 104 is 2 x 2 x 2 x 13

Prime Factorization of 26 is 2 x 13

Prime Factorization of 661 is 661

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(270, 104) = 14040

GCD(270, 104) = ( 270 x 104 ) / 14040

GCD(270, 104) = 28080 / 14040

GCD(270, 104) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 26

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

LCM(2, 26) = 26

GCD(2, 26) = ( 2 x 26 ) / 26

GCD(2, 26) = 52 / 26

GCD(2, 26) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 661

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

LCM(2, 661) = 1322

GCD(2, 661) = ( 2 x 661 ) / 1322

GCD(2, 661) = 1322 / 1322

GCD(2, 661) = 1

GCD of 270, 104, 26, 661 is 1
