Therefore, GCD of numbers 528, 620, 612, 657 is 1

Given Input Data is 528, 620, 612, 657

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

Prime Factorization of 528 is 2 x 2 x 2 x 2 x 3 x 11

Prime Factorization of 620 is 2 x 2 x 5 x 31

Prime Factorization of 612 is 2 x 2 x 3 x 3 x 17

Prime Factorization of 657 is 3 x 3 x 73

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(528, 620) = 81840

GCD(528, 620) = ( 528 x 620 ) / 81840

GCD(528, 620) = 327360 / 81840

GCD(528, 620) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 612

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

LCM(4, 612) = 612

GCD(4, 612) = ( 4 x 612 ) / 612

GCD(4, 612) = 2448 / 612

GCD(4, 612) = 4

Step3:

Here we consider the GCD from the above i.e. 4 as first number and the next as 657

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

LCM(4, 657) = 2628

GCD(4, 657) = ( 4 x 657 ) / 2628

GCD(4, 657) = 2628 / 2628

GCD(4, 657) = 1

GCD of 528, 620, 612, 657 is 1
