Given numbers are 85, 23, 83, 81

The list of prime factors of all numbers are

Prime factors of 85 are 5 x 17

Prime factors of 23 are 23

Prime factors of 83 are 83

Prime factors of 81 are 3 x 3 x 3 x 3

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

Given numbers are 85, 23, 83, 81

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

Apply this formula for all numbers.

Step1:

LCM(85, 23) = 1955

GCD(85, 23) = ( 85 x 23 ) / 1955

= 85 / 23

= 85

Step2:

LCM(1, 83) = 83

GCD(1, 83) = ( 1 x 83 ) / 83

= 1 / 83

= 1

Step3:

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

= 1 / 81

= 1

So, Greatest Common Divisor of 85, 23, 83, 81 is 1
