Given numbers are 309, 896, 668, 664

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

Apply this formula for all numbers.

Step1:

LCM(309, 896) = 276864

GCD(309, 896) = ( 309 x 896 ) / 276864

= 309 / 896

= 309

Step2:

LCM(1, 668) = 668

GCD(1, 668) = ( 1 x 668 ) / 668

= 1 / 668

= 1

Step3:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

So, Greatest Common Divisor of 309, 896, 668, 664 is 1
