Given numbers are 128, 366, 689

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

Apply this formula for all numbers.

Step1:

LCM(128, 366) = 23424

GCD(128, 366) = ( 128 x 366 ) / 23424

= 128 / 366

= 128

Step2:

LCM(2, 689) = 1378

GCD(2, 689) = ( 2 x 689 ) / 1378

= 2 / 689

= 2

So, Greatest Common Divisor of 128, 366, 689 is 1
