The list of prime factors of all numbers are

Prime factors of 678 are 2 x 3 x 113

Prime factors of 828 are 2 x 2 x 3 x 3 x 23

Prime factors of 221 are 13 x 17

Prime factors of 986 are 2 x 17 x 29

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

Given numbers are 678, 828, 221, 986

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

Apply this formula for all numbers.

Step1:

LCM(678, 828) = 93564

GCD(678, 828) = ( 678 x 828 ) / 93564

= 678 / 828

= 678

Step2:

LCM(6, 221) = 1326

GCD(6, 221) = ( 6 x 221 ) / 1326

= 6 / 221

= 6

Step3:

LCM(1, 986) = 986

GCD(1, 986) = ( 1 x 986 ) / 986

= 1 / 986

= 1

So, Greatest Common Divisor of 678, 828, 221, 986 is 1
