Given numbers are 777, 802, 819, 392

The list of prime factors of all numbers are

Prime factors of 777 are 3 x 7 x 37

Prime factors of 802 are 2 x 401

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 392 are 2 x 2 x 2 x 7 x 7

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

Given numbers are 777, 802, 819, 392

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

Apply this formula for all numbers.

Step1:

LCM(777, 802) = 623154

GCD(777, 802) = ( 777 x 802 ) / 623154

= 777 / 802

= 777

Step2:

LCM(1, 819) = 819

GCD(1, 819) = ( 1 x 819 ) / 819

= 1 / 819

= 1

Step3:

LCM(1, 392) = 392

GCD(1, 392) = ( 1 x 392 ) / 392

= 1 / 392

= 1

So, Greatest Common Divisor of 777, 802, 819, 392 is 1
