Given Input Data is 57, 380, 266, 440

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

Prime Factorization of 57 is 3 x 19

Prime Factorization of 380 is 2 x 2 x 5 x 19

Prime Factorization of 266 is 2 x 7 x 19

Prime Factorization of 440 is 2 x 2 x 2 x 5 x 11

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(57, 380) = 1140

GCD(57, 380) = ( 57 x 380 ) / 1140

GCD(57, 380) = 21660 / 1140

GCD(57, 380) = 19

Step2:

Here we consider the GCD from the above i.e. 19 as first number and the next as 266

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

LCM(19, 266) = 266

GCD(19, 266) = ( 19 x 266 ) / 266

GCD(19, 266) = 5054 / 266

GCD(19, 266) = 19

Step3:

Here we consider the GCD from the above i.e. 19 as first number and the next as 440

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

LCM(19, 440) = 8360

GCD(19, 440) = ( 19 x 440 ) / 8360

GCD(19, 440) = 8360 / 8360

GCD(19, 440) = 1

GCD of 57, 380, 266, 440 is 1
