Therefore, GCD of numbers 120, 178, 63, 911 is 1

Given Input Data is 120, 178, 63, 911

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

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

Prime Factorization of 178 is 2 x 89

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 911 is 911

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(120, 178) = 10680

GCD(120, 178) = ( 120 x 178 ) / 10680

GCD(120, 178) = 21360 / 10680

GCD(120, 178) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 63

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

LCM(2, 63) = 126

GCD(2, 63) = ( 2 x 63 ) / 126

GCD(2, 63) = 126 / 126

GCD(2, 63) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 911

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

LCM(1, 911) = 911

GCD(1, 911) = ( 1 x 911 ) / 911

GCD(1, 911) = 911 / 911

GCD(1, 911) = 1

GCD of 120, 178, 63, 911 is 1
