Given numbers are 678, 308, 369, 315

The list of prime factors of all numbers are

Prime factors of 678 are 2 x 3 x 113

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

Prime factors of 369 are 3 x 3 x 41

Prime factors of 315 are 3 x 3 x 5 x 7

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

Given numbers are 678, 308, 369, 315

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

Apply this formula for all numbers.

Step1:

LCM(678, 308) = 104412

GCD(678, 308) = ( 678 x 308 ) / 104412

= 678 / 308

= 678

Step2:

LCM(2, 369) = 738

GCD(2, 369) = ( 2 x 369 ) / 738

= 2 / 369

= 2

Step3:

LCM(1, 315) = 315

GCD(1, 315) = ( 1 x 315 ) / 315

= 1 / 315

= 1

So, Greatest Common Divisor of 678, 308, 369, 315 is 1
