Given numbers are 102, 561, 888, 865

The list of prime factors of all numbers are

Prime factors of 102 are 2 x 3 x 17

Prime factors of 561 are 3 x 11 x 17

Prime factors of 888 are 2 x 2 x 2 x 3 x 37

Prime factors of 865 are 5 x 173

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

Given numbers are 102, 561, 888, 865

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

Apply this formula for all numbers.

Step1:

LCM(102, 561) = 1122

GCD(102, 561) = ( 102 x 561 ) / 1122

= 102 / 561

= 102

Step2:

LCM(51, 888) = 15096

GCD(51, 888) = ( 51 x 888 ) / 15096

= 51 / 888

= 51

Step3:

LCM(3, 865) = 2595

GCD(3, 865) = ( 3 x 865 ) / 2595

= 3 / 865

= 3

So, Greatest Common Divisor of 102, 561, 888, 865 is 1
