Therefore, GCD of numbers 67, 28, 89 is 1

Given Input Data is 67, 28, 89

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

Prime Factorization of 67 is 67

Prime Factorization of 28 is 2 x 2 x 7

Prime Factorization of 89 is 89

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(67, 28) = 1876

GCD(67, 28) = ( 67 x 28 ) / 1876

GCD(67, 28) = 1876 / 1876

GCD(67, 28) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 89

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

LCM(1, 89) = 89

GCD(1, 89) = ( 1 x 89 ) / 89

GCD(1, 89) = 89 / 89

GCD(1, 89) = 1

GCD of 67, 28, 89 is 1
