Given Input Data is 552, 115, 402, 130

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

Prime Factorization of 552 is 2 x 2 x 2 x 3 x 23

Prime Factorization of 115 is 5 x 23

Prime Factorization of 402 is 2 x 3 x 67

Prime Factorization of 130 is 2 x 5 x 13

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(552, 115) = 2760

GCD(552, 115) = ( 552 x 115 ) / 2760

GCD(552, 115) = 63480 / 2760

GCD(552, 115) = 23

Step2:

Here we consider the GCD from the above i.e. 23 as first number and the next as 402

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

LCM(23, 402) = 9246

GCD(23, 402) = ( 23 x 402 ) / 9246

GCD(23, 402) = 9246 / 9246

GCD(23, 402) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 130

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

LCM(1, 130) = 130

GCD(1, 130) = ( 1 x 130 ) / 130

GCD(1, 130) = 130 / 130

GCD(1, 130) = 1

GCD of 552, 115, 402, 130 is 1
