Given numbers are 309, 642, 444, 313

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

Apply this formula for all numbers.

Step1:

LCM(309, 642) = 66126

GCD(309, 642) = ( 309 x 642 ) / 66126

= 309 / 642

= 309

Step2:

LCM(3, 444) = 444

GCD(3, 444) = ( 3 x 444 ) / 444

= 3 / 444

= 3

Step3:

LCM(3, 313) = 939

GCD(3, 313) = ( 3 x 313 ) / 939

= 3 / 313

= 3

So, Greatest Common Divisor of 309, 642, 444, 313 is 1
