Given numbers are 861, 567, 308, 339

The list of prime factors of all numbers are

Prime factors of 861 are 3 x 7 x 41

Prime factors of 567 are 3 x 3 x 3 x 3 x 7

Prime factors of 308 are 2 x 2 x 7 x 11

Prime factors of 339 are 3 x 113

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

Given numbers are 861, 567, 308, 339

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

Apply this formula for all numbers.

Step1:

LCM(861, 567) = 23247

GCD(861, 567) = ( 861 x 567 ) / 23247

= 861 / 567

= 861

Step2:

LCM(21, 308) = 924

GCD(21, 308) = ( 21 x 308 ) / 924

= 21 / 308

= 21

Step3:

LCM(7, 339) = 2373

GCD(7, 339) = ( 7 x 339 ) / 2373

= 7 / 339

= 7

So, Greatest Common Divisor of 861, 567, 308, 339 is 1
