Given Input Data is 575, 660, 755, 777

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

Prime Factorization of 575 is 5 x 5 x 23

Prime Factorization of 660 is 2 x 2 x 3 x 5 x 11

Prime Factorization of 755 is 5 x 151

Prime Factorization of 777 is 3 x 7 x 37

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(575, 660) = 75900

GCD(575, 660) = ( 575 x 660 ) / 75900

GCD(575, 660) = 379500 / 75900

GCD(575, 660) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 755

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

LCM(5, 755) = 755

GCD(5, 755) = ( 5 x 755 ) / 755

GCD(5, 755) = 3775 / 755

GCD(5, 755) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 777

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

LCM(5, 777) = 3885

GCD(5, 777) = ( 5 x 777 ) / 3885

GCD(5, 777) = 3885 / 3885

GCD(5, 777) = 1

GCD of 575, 660, 755, 777 is 1
