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

Apply this formula for all numbers.

Step1:

LCM(128, 768) = 768

GCD(128, 768) = ( 128 x 768 ) / 768

= 128 / 768

= 128

Step2:

LCM(128, 778) = 49792

GCD(128, 778) = ( 128 x 778 ) / 49792

= 128 / 778

= 128

So, Greatest Common Divisor of 128, 768, 778 is 2
