Given numbers are 639, 708, 361, 191

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

Apply this formula for all numbers.

Step1:

LCM(639, 708) = 150804

GCD(639, 708) = ( 639 x 708 ) / 150804

= 639 / 708

= 639

Step2:

LCM(3, 361) = 1083

GCD(3, 361) = ( 3 x 361 ) / 1083

= 3 / 361

= 3

Step3:

LCM(1, 191) = 191

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

= 1 / 191

= 1

So, Greatest Common Divisor of 639, 708, 361, 191 is 1
