Therefore, GCD of numbers 278, 454, 80, 777 is 1

Given Input Data is 278, 454, 80, 777

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

Prime Factorization of 278 is 2 x 139

Prime Factorization of 454 is 2 x 227

Prime Factorization of 80 is 2 x 2 x 2 x 2 x 5

Prime Factorization of 777 is 3 x 7 x 37

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(278, 454) = 63106

GCD(278, 454) = ( 278 x 454 ) / 63106

GCD(278, 454) = 126212 / 63106

GCD(278, 454) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 80

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

LCM(2, 80) = 80

GCD(2, 80) = ( 2 x 80 ) / 80

GCD(2, 80) = 160 / 80

GCD(2, 80) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 777

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

LCM(2, 777) = 1554

GCD(2, 777) = ( 2 x 777 ) / 1554

GCD(2, 777) = 1554 / 1554

GCD(2, 777) = 1

GCD of 278, 454, 80, 777 is 1
