Therefore, GCD of numbers 665, 570, 53, 963 is 1

Given Input Data is 665, 570, 53, 963

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

Prime Factorization of 665 is 5 x 7 x 19

Prime Factorization of 570 is 2 x 3 x 5 x 19

Prime Factorization of 53 is 53

Prime Factorization of 963 is 3 x 3 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(665, 570) = 3990

GCD(665, 570) = ( 665 x 570 ) / 3990

GCD(665, 570) = 379050 / 3990

GCD(665, 570) = 95

Step2:

Here we consider the GCD from the above i.e. 95 as first number and the next as 53

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

LCM(95, 53) = 5035

GCD(95, 53) = ( 95 x 53 ) / 5035

GCD(95, 53) = 5035 / 5035

GCD(95, 53) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 963

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

LCM(1, 963) = 963

GCD(1, 963) = ( 1 x 963 ) / 963

GCD(1, 963) = 963 / 963

GCD(1, 963) = 1

GCD of 665, 570, 53, 963 is 1
