Given numbers are 668, 664, 810, 128

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

Apply this formula for all numbers.

Step1:

LCM(668, 664) = 110888

GCD(668, 664) = ( 668 x 664 ) / 110888

= 668 / 664

= 668

Step2:

LCM(4, 810) = 1620

GCD(4, 810) = ( 4 x 810 ) / 1620

= 4 / 810

= 4

Step3:

LCM(2, 128) = 128

GCD(2, 128) = ( 2 x 128 ) / 128

= 2 / 128

= 2

So, Greatest Common Divisor of 668, 664, 810, 128 is 2
