Given numbers are 615, 308, 687, 368

The list of prime factors of all numbers are

Prime factors of 615 are 3 x 5 x 41

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

Prime factors of 687 are 3 x 229

Prime factors of 368 are 2 x 2 x 2 x 2 x 23

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

Given numbers are 615, 308, 687, 368

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

Apply this formula for all numbers.

Step1:

LCM(615, 308) = 189420

GCD(615, 308) = ( 615 x 308 ) / 189420

= 615 / 308

= 615

Step2:

LCM(1, 687) = 687

GCD(1, 687) = ( 1 x 687 ) / 687

= 1 / 687

= 1

Step3:

LCM(1, 368) = 368

GCD(1, 368) = ( 1 x 368 ) / 368

= 1 / 368

= 1

So, Greatest Common Divisor of 615, 308, 687, 368 is 1
