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

Apply this formula for all numbers.

Step1:

LCM(428, 820) = 87740

GCD(428, 820) = ( 428 x 820 ) / 87740

= 428 / 820

= 428

Step2:

LCM(4, 664) = 664

GCD(4, 664) = ( 4 x 664 ) / 664

= 4 / 664

= 4

So, Greatest Common Divisor of 428, 820, 664 is 4
