Therefore, GCD of numbers 245, 119, 54, 455 is 1

Given Input Data is 245, 119, 54, 455

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

Prime Factorization of 245 is 5 x 7 x 7

Prime Factorization of 119 is 7 x 17

Prime Factorization of 54 is 2 x 3 x 3 x 3

Prime Factorization of 455 is 5 x 7 x 13

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(245, 119) = 4165

GCD(245, 119) = ( 245 x 119 ) / 4165

GCD(245, 119) = 29155 / 4165

GCD(245, 119) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 54

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

LCM(7, 54) = 378

GCD(7, 54) = ( 7 x 54 ) / 378

GCD(7, 54) = 378 / 378

GCD(7, 54) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 455

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

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

GCD(1, 455) = 455 / 455

GCD(1, 455) = 1

GCD of 245, 119, 54, 455 is 1
