Given Input Data is 955, 668, 402, 135

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

Prime Factorization of 955 is 5 x 191

Prime Factorization of 668 is 2 x 2 x 167

Prime Factorization of 402 is 2 x 3 x 67

Prime Factorization of 135 is 3 x 3 x 3 x 5

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(955, 668) = 637940

GCD(955, 668) = ( 955 x 668 ) / 637940

GCD(955, 668) = 637940 / 637940

GCD(955, 668) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 402

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

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

GCD(1, 402) = 402 / 402

GCD(1, 402) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 135

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

LCM(1, 135) = 135

GCD(1, 135) = ( 1 x 135 ) / 135

GCD(1, 135) = 135 / 135

GCD(1, 135) = 1

GCD of 955, 668, 402, 135 is 1
