Given numbers are 421, 309, 444, 608

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

Apply this formula for all numbers.

Step1:

LCM(421, 309) = 130089

GCD(421, 309) = ( 421 x 309 ) / 130089

= 421 / 309

= 421

Step2:

LCM(1, 444) = 444

GCD(1, 444) = ( 1 x 444 ) / 444

= 1 / 444

= 1

Step3:

LCM(1, 608) = 608

GCD(1, 608) = ( 1 x 608 ) / 608

= 1 / 608

= 1

So, Greatest Common Divisor of 421, 309, 444, 608 is 1
