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

Apply this formula for all numbers.

Step1:

LCM(738, 664) = 245016

GCD(738, 664) = ( 738 x 664 ) / 245016

= 738 / 664

= 738

Step2:

LCM(2, 86) = 86

GCD(2, 86) = ( 2 x 86 ) / 86

= 2 / 86

= 2

Step3:

LCM(2, 638) = 638

GCD(2, 638) = ( 2 x 638 ) / 638

= 2 / 638

= 2

So, Greatest Common Divisor of 738, 664, 86, 638 is 2
