Given Input Data is 955, 558, 975, 991

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

Prime Factorization of 955 is 5 x 191

Prime Factorization of 558 is 2 x 3 x 3 x 31

Prime Factorization of 975 is 3 x 5 x 5 x 13

Prime Factorization of 991 is 991

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, 558) = 532890

GCD(955, 558) = ( 955 x 558 ) / 532890

GCD(955, 558) = 532890 / 532890

GCD(955, 558) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 975

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

LCM(1, 975) = 975

GCD(1, 975) = ( 1 x 975 ) / 975

GCD(1, 975) = 975 / 975

GCD(1, 975) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 991

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

LCM(1, 991) = 991

GCD(1, 991) = ( 1 x 991 ) / 991

GCD(1, 991) = 991 / 991

GCD(1, 991) = 1

GCD of 955, 558, 975, 991 is 1
