GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(255, 438) = 37230
GCD(255, 438) = ( 255 x 438 ) / 37230
= 255 / 438
= 255
Step2:
LCM(3, 618) = 618
GCD(3, 618) = ( 3 x 618 ) / 618
= 3 / 618
= 3
Step3:
LCM(3, 192) = 192
GCD(3, 192) = ( 3 x 192 ) / 192
= 3 / 192
= 3
So, Greatest Common Divisor of 255, 438, 618, 192 is 3
