Given numbers are 398, 226, 634, 664

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

Apply this formula for all numbers.

Step1:

LCM(398, 226) = 44974

GCD(398, 226) = ( 398 x 226 ) / 44974

= 398 / 226

= 398

Step2:

LCM(2, 634) = 634

GCD(2, 634) = ( 2 x 634 ) / 634

= 2 / 634

= 2

Step3:

LCM(2, 664) = 664

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

= 2 / 664

= 2

So, Greatest Common Divisor of 398, 226, 634, 664 is 2
