Therefore, GCD of numbers 245, 189, 67, 965 is 1

Given Input Data is 245, 189, 67, 965

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

Prime Factorization of 245 is 5 x 7 x 7

Prime Factorization of 189 is 3 x 3 x 3 x 7

Prime Factorization of 67 is 67

Prime Factorization of 965 is 5 x 193

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(245, 189) = 6615

GCD(245, 189) = ( 245 x 189 ) / 6615

GCD(245, 189) = 46305 / 6615

GCD(245, 189) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 67

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

LCM(7, 67) = 469

GCD(7, 67) = ( 7 x 67 ) / 469

GCD(7, 67) = 469 / 469

GCD(7, 67) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 965

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

LCM(1, 965) = 965

GCD(1, 965) = ( 1 x 965 ) / 965

GCD(1, 965) = 965 / 965

GCD(1, 965) = 1

GCD of 245, 189, 67, 965 is 1
