Therefore, GCD of numbers 33, 678, 397, 788 is 1

Given Input Data is 33, 678, 397, 788

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

Prime Factorization of 33 is 3 x 11

Prime Factorization of 678 is 2 x 3 x 113

Prime Factorization of 397 is 397

Prime Factorization of 788 is 2 x 2 x 197

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(33, 678) = 7458

GCD(33, 678) = ( 33 x 678 ) / 7458

GCD(33, 678) = 22374 / 7458

GCD(33, 678) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 397

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

LCM(3, 397) = 1191

GCD(3, 397) = ( 3 x 397 ) / 1191

GCD(3, 397) = 1191 / 1191

GCD(3, 397) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 788

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

LCM(1, 788) = 788

GCD(1, 788) = ( 1 x 788 ) / 788

GCD(1, 788) = 788 / 788

GCD(1, 788) = 1

GCD of 33, 678, 397, 788 is 1
