Given numbers are 815, 861, 101, 328

The list of prime factors of all numbers are

Prime factors of 815 are 5 x 163

Prime factors of 861 are 3 x 7 x 41

Prime factors of 101 are 101

Prime factors of 328 are 2 x 2 x 2 x 41

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

Given numbers are 815, 861, 101, 328

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

Apply this formula for all numbers.

Step1:

LCM(815, 861) = 701715

GCD(815, 861) = ( 815 x 861 ) / 701715

= 815 / 861

= 815

Step2:

LCM(1, 101) = 101

GCD(1, 101) = ( 1 x 101 ) / 101

= 1 / 101

= 1

Step3:

LCM(1, 328) = 328

GCD(1, 328) = ( 1 x 328 ) / 328

= 1 / 328

= 1

So, Greatest Common Divisor of 815, 861, 101, 328 is 1
