The list of prime factors of all numbers are

Prime factors of 662 are 2 x 331

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

Prime factors of 205 are 5 x 41

Prime factors of 815 are 5 x 163

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

Given numbers are 662, 308, 205, 815

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

Apply this formula for all numbers.

Step1:

LCM(662, 308) = 101948

GCD(662, 308) = ( 662 x 308 ) / 101948

= 662 / 308

= 662

Step2:

LCM(2, 205) = 410

GCD(2, 205) = ( 2 x 205 ) / 410

= 2 / 205

= 2

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 662, 308, 205, 815 is 1
