Therefore, GCD of numbers 663, 153, 40, 773 is 1

Given Input Data is 663, 153, 40, 773

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 153 is 3 x 3 x 17

Prime Factorization of 40 is 2 x 2 x 2 x 5

Prime Factorization of 773 is 773

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, 153) = 1989

GCD(663, 153) = ( 663 x 153 ) / 1989

GCD(663, 153) = 101439 / 1989

GCD(663, 153) = 51

Step2:

Here we consider the GCD from the above i.e. 51 as first number and the next as 40

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

LCM(51, 40) = 2040

GCD(51, 40) = ( 51 x 40 ) / 2040

GCD(51, 40) = 2040 / 2040

GCD(51, 40) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 773

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

LCM(1, 773) = 773

GCD(1, 773) = ( 1 x 773 ) / 773

GCD(1, 773) = 773 / 773

GCD(1, 773) = 1

GCD of 663, 153, 40, 773 is 1
