Given numbers are 665, 380, 664, 963

The list of prime factors of all numbers are

Prime factors of 665 are 5 x 7 x 19

Prime factors of 380 are 2 x 2 x 5 x 19

Prime factors of 664 are 2 x 2 x 2 x 83

Prime factors of 963 are 3 x 3 x 107

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 665, 380, 664, 963

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(665, 380) = 2660

GCD(665, 380) = ( 665 x 380 ) / 2660

= 665 / 380

= 665

Step2:

LCM(95, 664) = 63080

GCD(95, 664) = ( 95 x 664 ) / 63080

= 95 / 664

= 95

Step3:

LCM(1, 963) = 963

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

= 1 / 963

= 1

So, Greatest Common Divisor of 665, 380, 664, 963 is 1
