The list of prime factors of all numbers are

Prime factors of 865 are 5 x 173

Prime factors of 501 are 3 x 167

Prime factors of 275 are 5 x 5 x 11

Prime factors of 639 are 3 x 3 x 71

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

Given numbers are 865, 501, 275, 639

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

Apply this formula for all numbers.

Step1:

LCM(865, 501) = 433365

GCD(865, 501) = ( 865 x 501 ) / 433365

= 865 / 501

= 865

Step2:

LCM(1, 275) = 275

GCD(1, 275) = ( 1 x 275 ) / 275

= 1 / 275

= 1

Step3:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 865, 501, 275, 639 is 1
