Given numbers are 777, 696, 664, 489

The list of prime factors of all numbers are

Prime factors of 777 are 3 x 7 x 37

Prime factors of 696 are 2 x 2 x 2 x 3 x 29

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

Prime factors of 489 are 3 x 163

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

Given numbers are 777, 696, 664, 489

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

Apply this formula for all numbers.

Step1:

LCM(777, 696) = 180264

GCD(777, 696) = ( 777 x 696 ) / 180264

= 777 / 696

= 777

Step2:

LCM(3, 664) = 1992

GCD(3, 664) = ( 3 x 664 ) / 1992

= 3 / 664

= 3

Step3:

LCM(1, 489) = 489

GCD(1, 489) = ( 1 x 489 ) / 489

= 1 / 489

= 1

So, Greatest Common Divisor of 777, 696, 664, 489 is 1
