Given numbers are 777, 122, 690, 191

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

Apply this formula for all numbers.

Step1:

LCM(777, 122) = 94794

GCD(777, 122) = ( 777 x 122 ) / 94794

= 777 / 122

= 777

Step2:

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

= 1 / 690

= 1

Step3:

LCM(1, 191) = 191

GCD(1, 191) = ( 1 x 191 ) / 191

= 1 / 191

= 1

So, Greatest Common Divisor of 777, 122, 690, 191 is 1
