Given numbers are 128, 942, 934, 645

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

Apply this formula for all numbers.

Step1:

LCM(128, 942) = 60288

GCD(128, 942) = ( 128 x 942 ) / 60288

= 128 / 942

= 128

Step2:

LCM(2, 934) = 934

GCD(2, 934) = ( 2 x 934 ) / 934

= 2 / 934

= 2

Step3:

LCM(2, 645) = 1290

GCD(2, 645) = ( 2 x 645 ) / 1290

= 2 / 645

= 2

So, Greatest Common Divisor of 128, 942, 934, 645 is 1
