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

Apply this formula for all numbers.

Step1:

LCM(664, 978) = 324696

GCD(664, 978) = ( 664 x 978 ) / 324696

= 664 / 978

= 664

Step2:

LCM(2, 399) = 798

GCD(2, 399) = ( 2 x 399 ) / 798

= 2 / 399

= 2

Step3:

LCM(1, 592) = 592

GCD(1, 592) = ( 1 x 592 ) / 592

= 1 / 592

= 1

So, Greatest Common Divisor of 664, 978, 399, 592 is 1
