Given numbers are 181, 645, 939, 664

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

Apply this formula for all numbers.

Step1:

LCM(181, 645) = 116745

GCD(181, 645) = ( 181 x 645 ) / 116745

= 181 / 645

= 181

Step2:

LCM(1, 939) = 939

GCD(1, 939) = ( 1 x 939 ) / 939

= 1 / 939

= 1

Step3:

LCM(1, 664) = 664

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

= 1 / 664

= 1

So, Greatest Common Divisor of 181, 645, 939, 664 is 1
