The list of prime factors of all numbers are

Prime factors of 678 are 2 x 3 x 113

Prime factors of 646 are 2 x 17 x 19

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

Prime factors of 889 are 7 x 127

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

Given numbers are 678, 646, 660, 889

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

Apply this formula for all numbers.

Step1:

LCM(678, 646) = 218994

GCD(678, 646) = ( 678 x 646 ) / 218994

= 678 / 646

= 678

Step2:

LCM(2, 660) = 660

GCD(2, 660) = ( 2 x 660 ) / 660

= 2 / 660

= 2

Step3:

LCM(2, 889) = 1778

GCD(2, 889) = ( 2 x 889 ) / 1778

= 2 / 889

= 2

So, Greatest Common Divisor of 678, 646, 660, 889 is 1
