Given numbers are 555, 664, 499, 390

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

Apply this formula for all numbers.

Step1:

LCM(555, 664) = 368520

GCD(555, 664) = ( 555 x 664 ) / 368520

= 555 / 664

= 555

Step2:

LCM(1, 499) = 499

GCD(1, 499) = ( 1 x 499 ) / 499

= 1 / 499

= 1

Step3:

LCM(1, 390) = 390

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

= 1 / 390

= 1

So, Greatest Common Divisor of 555, 664, 499, 390 is 1
