Given numbers are 389, 308, 632, 921

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

Apply this formula for all numbers.

Step1:

LCM(389, 308) = 119812

GCD(389, 308) = ( 389 x 308 ) / 119812

= 389 / 308

= 389

Step2:

LCM(1, 632) = 632

GCD(1, 632) = ( 1 x 632 ) / 632

= 1 / 632

= 1

Step3:

LCM(1, 921) = 921

GCD(1, 921) = ( 1 x 921 ) / 921

= 1 / 921

= 1

So, Greatest Common Divisor of 389, 308, 632, 921 is 1
