Given numbers are 128, 548, 691

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

Apply this formula for all numbers.

Step1:

LCM(128, 548) = 17536

GCD(128, 548) = ( 128 x 548 ) / 17536

= 128 / 548

= 128

Step2:

LCM(4, 691) = 2764

GCD(4, 691) = ( 4 x 691 ) / 2764

= 4 / 691

= 4

So, Greatest Common Divisor of 128, 548, 691 is 1
