Given numbers are 154, 406, 174, 664

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

Apply this formula for all numbers.

Step1:

LCM(154, 406) = 4466

GCD(154, 406) = ( 154 x 406 ) / 4466

= 154 / 406

= 154

Step2:

LCM(14, 174) = 1218

GCD(14, 174) = ( 14 x 174 ) / 1218

= 14 / 174

= 14

Step3:

LCM(2, 664) = 664

GCD(2, 664) = ( 2 x 664 ) / 664

= 2 / 664

= 2

So, Greatest Common Divisor of 154, 406, 174, 664 is 2
