We found the divisors of 78, 41, 69, 69 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 78, 41, 69, 69 is 1.

Therefore, GCD of numbers 78, 41, 69, 69 is 1

Given Input Data is 78, 41, 69, 69

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

Prime Factorization of 78 is 2 x 3 x 13

Prime Factorization of 41 is 41

Prime Factorization of 69 is 3 x 23

Prime Factorization of 69 is 3 x 23

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(78, 41) = 3198

GCD(78, 41) = ( 78 x 41 ) / 3198

GCD(78, 41) = 3198 / 3198

GCD(78, 41) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 69

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

LCM(1, 69) = 69

GCD(1, 69) = ( 1 x 69 ) / 69

GCD(1, 69) = 69 / 69

GCD(1, 69) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 69

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

LCM(1, 69) = 69

GCD(1, 69) = ( 1 x 69 ) / 69

GCD(1, 69) = 69 / 69

GCD(1, 69) = 1

GCD of 78, 41, 69, 69 is 1
