Given Input Data is 455, 338, 757

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

Prime Factorization of 455 is 5 x 7 x 13

Prime Factorization of 338 is 2 x 13 x 13

Prime Factorization of 757 is 757

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(455, 338) = 11830

GCD(455, 338) = ( 455 x 338 ) / 11830

GCD(455, 338) = 153790 / 11830

GCD(455, 338) = 13

Step2:

Here we consider the GCD from the above i.e. 13 as first number and the next as 757

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

LCM(13, 757) = 9841

GCD(13, 757) = ( 13 x 757 ) / 9841

GCD(13, 757) = 9841 / 9841

GCD(13, 757) = 1

GCD of 455, 338, 757 is 1
