Given numbers are 89, 85, 54, 47

The list of prime factors of all numbers are

Prime factors of 89 are 89

Prime factors of 85 are 5 x 17

Prime factors of 54 are 2 x 3 x 3 x 3

Prime factors of 47 are 47

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

Given numbers are 89, 85, 54, 47

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

Apply this formula for all numbers.

Step1:

LCM(89, 85) = 7565

GCD(89, 85) = ( 89 x 85 ) / 7565

= 89 / 85

= 89

Step2:

LCM(1, 54) = 54

GCD(1, 54) = ( 1 x 54 ) / 54

= 1 / 54

= 1

Step3:

LCM(1, 47) = 47

GCD(1, 47) = ( 1 x 47 ) / 47

= 1 / 47

= 1

So, Greatest Common Divisor of 89, 85, 54, 47 is 1
