Given numbers are 328, 663, 811, 197

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

Apply this formula for all numbers.

Step1:

LCM(328, 663) = 217464

GCD(328, 663) = ( 328 x 663 ) / 217464

= 328 / 663

= 328

Step2:

LCM(1, 811) = 811

GCD(1, 811) = ( 1 x 811 ) / 811

= 1 / 811

= 1

Step3:

LCM(1, 197) = 197

GCD(1, 197) = ( 1 x 197 ) / 197

= 1 / 197

= 1

So, Greatest Common Divisor of 328, 663, 811, 197 is 1
