Given numbers are 639, 666, 777, 608

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

Apply this formula for all numbers.

Step1:

LCM(639, 666) = 47286

GCD(639, 666) = ( 639 x 666 ) / 47286

= 639 / 666

= 639

Step2:

LCM(9, 777) = 2331

GCD(9, 777) = ( 9 x 777 ) / 2331

= 9 / 777

= 9

Step3:

LCM(3, 608) = 1824

GCD(3, 608) = ( 3 x 608 ) / 1824

= 3 / 608

= 3

So, Greatest Common Divisor of 639, 666, 777, 608 is 1
