Given numbers are 116, 390, 401, 128

The list of prime factors of all numbers are

Prime factors of 116 are 2 x 2 x 29

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 401 are 401

Prime factors of 128 are 2 x 2 x 2 x 2 x 2 x 2 x 2

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 116, 390, 401, 128

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

Apply this formula for all numbers.

Step1:

LCM(116, 390) = 22620

GCD(116, 390) = ( 116 x 390 ) / 22620

= 116 / 390

= 116

Step2:

LCM(2, 401) = 802

GCD(2, 401) = ( 2 x 401 ) / 802

= 2 / 401

= 2

Step3:

LCM(1, 128) = 128

GCD(1, 128) = ( 1 x 128 ) / 128

= 1 / 128

= 1

So, Greatest Common Divisor of 116, 390, 401, 128 is 1
