Given numbers are 208, 540, 391, 192

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

Apply this formula for all numbers.

Step1:

LCM(208, 540) = 28080

GCD(208, 540) = ( 208 x 540 ) / 28080

= 208 / 540

= 208

Step2:

LCM(4, 391) = 1564

GCD(4, 391) = ( 4 x 391 ) / 1564

= 4 / 391

= 4

Step3:

LCM(1, 192) = 192

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

= 1 / 192

= 1

So, Greatest Common Divisor of 208, 540, 391, 192 is 1
