Therefore, GCD of numbers 451, 120, 665 is 1

Given Input Data is 451, 120, 665

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

Prime Factorization of 451 is 11 x 41

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

Prime Factorization of 665 is 5 x 7 x 19

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(451, 120) = 54120

GCD(451, 120) = ( 451 x 120 ) / 54120

GCD(451, 120) = 54120 / 54120

GCD(451, 120) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 665

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

LCM(1, 665) = 665

GCD(1, 665) = ( 1 x 665 ) / 665

GCD(1, 665) = 665 / 665

GCD(1, 665) = 1

GCD of 451, 120, 665 is 1
