Therefore, GCD of numbers 84, 66, 39, 26 is 1

Given Input Data is 84, 66, 39, 26

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

Prime Factorization of 84 is 2 x 2 x 3 x 7

Prime Factorization of 66 is 2 x 3 x 11

Prime Factorization of 39 is 3 x 13

Prime Factorization of 26 is 2 x 13

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(84, 66) = 924

GCD(84, 66) = ( 84 x 66 ) / 924

GCD(84, 66) = 5544 / 924

GCD(84, 66) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 39

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

LCM(6, 39) = 78

GCD(6, 39) = ( 6 x 39 ) / 78

GCD(6, 39) = 234 / 78

GCD(6, 39) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 26

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

LCM(3, 26) = 78

GCD(3, 26) = ( 3 x 26 ) / 78

GCD(3, 26) = 78 / 78

GCD(3, 26) = 1

GCD of 84, 66, 39, 26 is 1
