Given numbers are 128, 380, 659, 769

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

Apply this formula for all numbers.

Step1:

LCM(128, 380) = 12160

GCD(128, 380) = ( 128 x 380 ) / 12160

= 128 / 380

= 128

Step2:

LCM(4, 659) = 2636

GCD(4, 659) = ( 4 x 659 ) / 2636

= 4 / 659

= 4

Step3:

LCM(1, 769) = 769

GCD(1, 769) = ( 1 x 769 ) / 769

= 1 / 769

= 1

So, Greatest Common Divisor of 128, 380, 659, 769 is 1
