Given numbers are 663, 328, 877, 390

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

Apply this formula for all numbers.

Step1:

LCM(663, 328) = 217464

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

= 663 / 328

= 663

Step2:

LCM(1, 877) = 877

GCD(1, 877) = ( 1 x 877 ) / 877

= 1 / 877

= 1

Step3:

LCM(1, 390) = 390

GCD(1, 390) = ( 1 x 390 ) / 390

= 1 / 390

= 1

So, Greatest Common Divisor of 663, 328, 877, 390 is 1
