Given numbers are 946, 128, 28, 969

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

Apply this formula for all numbers.

Step1:

LCM(946, 128) = 60544

GCD(946, 128) = ( 946 x 128 ) / 60544

= 946 / 128

= 946

Step2:

LCM(2, 28) = 28

GCD(2, 28) = ( 2 x 28 ) / 28

= 2 / 28

= 2

Step3:

LCM(2, 969) = 1938

GCD(2, 969) = ( 2 x 969 ) / 1938

= 2 / 969

= 2

So, Greatest Common Divisor of 946, 128, 28, 969 is 1
