Therefore, GCD of numbers 207, 146, 551, 428 is 1

Given Input Data is 207, 146, 551, 428

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

Prime Factorization of 207 is 3 x 3 x 23

Prime Factorization of 146 is 2 x 73

Prime Factorization of 551 is 19 x 29

Prime Factorization of 428 is 2 x 2 x 107

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(207, 146) = 30222

GCD(207, 146) = ( 207 x 146 ) / 30222

GCD(207, 146) = 30222 / 30222

GCD(207, 146) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 551

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

LCM(1, 551) = 551

GCD(1, 551) = ( 1 x 551 ) / 551

GCD(1, 551) = 551 / 551

GCD(1, 551) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 428

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

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

GCD(1, 428) = 428 / 428

GCD(1, 428) = 1

GCD of 207, 146, 551, 428 is 1
