Therefore, GCD of numbers 84, 777, 551, 851 is 1

Given Input Data is 84, 777, 551, 851

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 777 is 3 x 7 x 37

Prime Factorization of 551 is 19 x 29

Prime Factorization of 851 is 23 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(84, 777) = 3108

GCD(84, 777) = ( 84 x 777 ) / 3108

GCD(84, 777) = 65268 / 3108

GCD(84, 777) = 21

Step2:

Here we consider the GCD from the above i.e. 21 as first number and the next as 551

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

LCM(21, 551) = 11571

GCD(21, 551) = ( 21 x 551 ) / 11571

GCD(21, 551) = 11571 / 11571

GCD(21, 551) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 851

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

LCM(1, 851) = 851

GCD(1, 851) = ( 1 x 851 ) / 851

GCD(1, 851) = 851 / 851

GCD(1, 851) = 1

GCD of 84, 777, 551, 851 is 1
