Given numbers are 639, 548, 392, 192

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

Apply this formula for all numbers.

Step1:

LCM(639, 548) = 350172

GCD(639, 548) = ( 639 x 548 ) / 350172

= 639 / 548

= 639

Step2:

LCM(1, 392) = 392

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

= 1 / 392

= 1

Step3:

LCM(1, 192) = 192

GCD(1, 192) = ( 1 x 192 ) / 192

= 1 / 192

= 1

So, Greatest Common Divisor of 639, 548, 392, 192 is 1
