Given numbers are 57, 15, 85, 89

The list of prime factors of all numbers are

Prime factors of 57 are 3 x 19

Prime factors of 15 are 3 x 5

Prime factors of 85 are 5 x 17

Prime factors of 89 are 89

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

Given numbers are 57, 15, 85, 89

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

Apply this formula for all numbers.

Step1:

LCM(57, 15) = 285

GCD(57, 15) = ( 57 x 15 ) / 285

= 57 / 15

= 57

Step2:

LCM(3, 85) = 255

GCD(3, 85) = ( 3 x 85 ) / 255

= 3 / 85

= 3

Step3:

LCM(1, 89) = 89

GCD(1, 89) = ( 1 x 89 ) / 89

= 1 / 89

= 1

So, Greatest Common Divisor of 57, 15, 85, 89 is 1
