Therefore, GCD of numbers 84, 663, 877, 120 is 1

Given Input Data is 84, 663, 877, 120

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 663 is 3 x 13 x 17

Prime Factorization of 877 is 877

Prime Factorization of 120 is 2 x 2 x 2 x 3 x 5

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, 663) = 18564

GCD(84, 663) = ( 84 x 663 ) / 18564

GCD(84, 663) = 55692 / 18564

GCD(84, 663) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 877

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

LCM(3, 877) = 2631

GCD(3, 877) = ( 3 x 877 ) / 2631

GCD(3, 877) = 2631 / 2631

GCD(3, 877) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 120

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

LCM(1, 120) = 120

GCD(1, 120) = ( 1 x 120 ) / 120

GCD(1, 120) = 120 / 120

GCD(1, 120) = 1

GCD of 84, 663, 877, 120 is 1
