GCD of numbers is the greatest common divisor

So, the GCD (20, 38, 89, 95) = 1.

Given numbers are 20, 38, 89, 95

The list of prime factors of all numbers are

Prime factors of 20 are 2 x 2 x 5

Prime factors of 38 are 2 x 19

Prime factors of 89 are 89

Prime factors of 95 are 5 x 19

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

Given numbers are 20, 38, 89, 95

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

Apply this formula for all numbers.

Step1:

LCM(20, 38) = 380

GCD(20, 38) = ( 20 x 38 ) / 380

= 20 / 38

= 20

Step2:

LCM(2, 89) = 178

GCD(2, 89) = ( 2 x 89 ) / 178

= 2 / 89

= 2

Step3:

LCM(1, 95) = 95

GCD(1, 95) = ( 1 x 95 ) / 95

= 1 / 95

= 1

So, Greatest Common Divisor of 20, 38, 89, 95 is 1
