Given numbers are 664, 258, 256, 285

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

Apply this formula for all numbers.

Step1:

LCM(664, 258) = 85656

GCD(664, 258) = ( 664 x 258 ) / 85656

= 664 / 258

= 664

Step2:

LCM(2, 256) = 256

GCD(2, 256) = ( 2 x 256 ) / 256

= 2 / 256

= 2

Step3:

LCM(2, 285) = 570

GCD(2, 285) = ( 2 x 285 ) / 570

= 2 / 285

= 2

So, Greatest Common Divisor of 664, 258, 256, 285 is 1
