The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 913 are 11 x 83

Prime factors of 407 are 11 x 37

Prime factors of 329 are 7 x 47

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

Given numbers are 861, 913, 407, 329

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

Apply this formula for all numbers.

Step1:

LCM(861, 913) = 786093

GCD(861, 913) = ( 861 x 913 ) / 786093

= 861 / 913

= 861

Step2:

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

= 1 / 407

= 1

Step3:

LCM(1, 329) = 329

GCD(1, 329) = ( 1 x 329 ) / 329

= 1 / 329

= 1

So, Greatest Common Divisor of 861, 913, 407, 329 is 1
