Given numbers are 203, 365, 664, 820

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

Apply this formula for all numbers.

Step1:

LCM(203, 365) = 74095

GCD(203, 365) = ( 203 x 365 ) / 74095

= 203 / 365

= 203

Step2:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

Step3:

LCM(1, 820) = 820

GCD(1, 820) = ( 1 x 820 ) / 820

= 1 / 820

= 1

So, Greatest Common Divisor of 203, 365, 664, 820 is 1
