Given numbers are 128, 194, 432, 520

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

Apply this formula for all numbers.

Step1:

LCM(128, 194) = 12416

GCD(128, 194) = ( 128 x 194 ) / 12416

= 128 / 194

= 128

Step2:

LCM(2, 432) = 432

GCD(2, 432) = ( 2 x 432 ) / 432

= 2 / 432

= 2

Step3:

LCM(2, 520) = 520

GCD(2, 520) = ( 2 x 520 ) / 520

= 2 / 520

= 2

So, Greatest Common Divisor of 128, 194, 432, 520 is 2
