The list of prime factors of all numbers are

Prime factors of 678 are 2 x 3 x 113

Prime factors of 231 are 3 x 7 x 11

Prime factors of 869 are 11 x 79

Prime factors of 545 are 5 x 109

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

Given numbers are 678, 231, 869, 545

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

Apply this formula for all numbers.

Step1:

LCM(678, 231) = 52206

GCD(678, 231) = ( 678 x 231 ) / 52206

= 678 / 231

= 678

Step2:

LCM(3, 869) = 2607

GCD(3, 869) = ( 3 x 869 ) / 2607

= 3 / 869

= 3

Step3:

LCM(1, 545) = 545

GCD(1, 545) = ( 1 x 545 ) / 545

= 1 / 545

= 1

So, Greatest Common Divisor of 678, 231, 869, 545 is 1
