Therefore, GCD of numbers 663, 884, 761, 406 is 1

Given Input Data is 663, 884, 761, 406

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

Prime Factorization of 663 is 3 x 13 x 17

Prime Factorization of 884 is 2 x 2 x 13 x 17

Prime Factorization of 761 is 761

Prime Factorization of 406 is 2 x 7 x 29

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(663, 884) = 2652

GCD(663, 884) = ( 663 x 884 ) / 2652

GCD(663, 884) = 586092 / 2652

GCD(663, 884) = 221

Step2:

Here we consider the GCD from the above i.e. 221 as first number and the next as 761

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

LCM(221, 761) = 168181

GCD(221, 761) = ( 221 x 761 ) / 168181

GCD(221, 761) = 168181 / 168181

GCD(221, 761) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 406

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

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

GCD(1, 406) = 406 / 406

GCD(1, 406) = 1

GCD of 663, 884, 761, 406 is 1
