Given numbers are 128, 947, 657

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

Apply this formula for all numbers.

Step1:

LCM(128, 947) = 121216

GCD(128, 947) = ( 128 x 947 ) / 121216

= 128 / 947

= 128

Step2:

LCM(1, 657) = 657

GCD(1, 657) = ( 1 x 657 ) / 657

= 1 / 657

= 1

So, Greatest Common Divisor of 128, 947, 657 is 1
