Given numbers are 678, 220, 819, 220

The list of prime factors of all numbers are

Prime factors of 678 are 2 x 3 x 113

Prime factors of 220 are 2 x 2 x 5 x 11

Prime factors of 819 are 3 x 3 x 7 x 13

Prime factors of 220 are 2 x 2 x 5 x 11

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

Given numbers are 678, 220, 819, 220

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

Apply this formula for all numbers.

Step1:

LCM(678, 220) = 74580

GCD(678, 220) = ( 678 x 220 ) / 74580

= 678 / 220

= 678

Step2:

LCM(2, 819) = 1638

GCD(2, 819) = ( 2 x 819 ) / 1638

= 2 / 819

= 2

Step3:

LCM(1, 220) = 220

GCD(1, 220) = ( 1 x 220 ) / 220

= 1 / 220

= 1

So, Greatest Common Divisor of 678, 220, 819, 220 is 1
