Given numbers are 664, 397, 321, 518

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

Apply this formula for all numbers.

Step1:

LCM(664, 397) = 263608

GCD(664, 397) = ( 664 x 397 ) / 263608

= 664 / 397

= 664

Step2:

LCM(1, 321) = 321

GCD(1, 321) = ( 1 x 321 ) / 321

= 1 / 321

= 1

Step3:

LCM(1, 518) = 518

GCD(1, 518) = ( 1 x 518 ) / 518

= 1 / 518

= 1

So, Greatest Common Divisor of 664, 397, 321, 518 is 1
