Therefore, GCD of numbers 639, 663, 11, 160 is 1

Given Input Data is 639, 663, 11, 160

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

Prime Factorization of 639 is 3 x 3 x 71

Prime Factorization of 663 is 3 x 13 x 17

Prime Factorization of 11 is 11

Prime Factorization of 160 is 2 x 2 x 2 x 2 x 2 x 5

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(639, 663) = 141219

GCD(639, 663) = ( 639 x 663 ) / 141219

GCD(639, 663) = 423657 / 141219

GCD(639, 663) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 11

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

LCM(3, 11) = 33

GCD(3, 11) = ( 3 x 11 ) / 33

GCD(3, 11) = 33 / 33

GCD(3, 11) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 160

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

LCM(1, 160) = 160

GCD(1, 160) = ( 1 x 160 ) / 160

GCD(1, 160) = 160 / 160

GCD(1, 160) = 1

GCD of 639, 663, 11, 160 is 1
