Therefore, GCD of numbers 995, 775, 78, 122 is 1

Given Input Data is 995, 775, 78, 122

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

Prime Factorization of 995 is 5 x 199

Prime Factorization of 775 is 5 x 5 x 31

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 122 is 2 x 61

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(995, 775) = 154225

GCD(995, 775) = ( 995 x 775 ) / 154225

GCD(995, 775) = 771125 / 154225

GCD(995, 775) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 78

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

LCM(5, 78) = 390

GCD(5, 78) = ( 5 x 78 ) / 390

GCD(5, 78) = 390 / 390

GCD(5, 78) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 122

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

LCM(1, 122) = 122

GCD(1, 122) = ( 1 x 122 ) / 122

GCD(1, 122) = 122 / 122

GCD(1, 122) = 1

GCD of 995, 775, 78, 122 is 1
