Given numbers are 666, 489, 428, 575

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

Apply this formula for all numbers.

Step1:

LCM(666, 489) = 108558

GCD(666, 489) = ( 666 x 489 ) / 108558

= 666 / 489

= 666

Step2:

LCM(3, 428) = 1284

GCD(3, 428) = ( 3 x 428 ) / 1284

= 3 / 428

= 3

Step3:

LCM(1, 575) = 575

GCD(1, 575) = ( 1 x 575 ) / 575

= 1 / 575

= 1

So, Greatest Common Divisor of 666, 489, 428, 575 is 1
