Therefore, GCD of numbers 488, 428, 823, 388 is 1

Given Input Data is 488, 428, 823, 388

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

Prime Factorization of 488 is 2 x 2 x 2 x 61

Prime Factorization of 428 is 2 x 2 x 107

Prime Factorization of 823 is 823

Prime Factorization of 388 is 2 x 2 x 97

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(488, 428) = 52216

GCD(488, 428) = ( 488 x 428 ) / 52216

GCD(488, 428) = 208864 / 52216

GCD(488, 428) = 4

Step2:

Here we consider the GCD from the above i.e. 4 as first number and the next as 823

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

LCM(4, 823) = 3292

GCD(4, 823) = ( 4 x 823 ) / 3292

GCD(4, 823) = 3292 / 3292

GCD(4, 823) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 388

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

LCM(1, 388) = 388

GCD(1, 388) = ( 1 x 388 ) / 388

GCD(1, 388) = 388 / 388

GCD(1, 388) = 1

GCD of 488, 428, 823, 388 is 1
