Given numbers are 627, 815, 620, 308

The list of prime factors of all numbers are

Prime factors of 627 are 3 x 11 x 19

Prime factors of 815 are 5 x 163

Prime factors of 620 are 2 x 2 x 5 x 31

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

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

Given numbers are 627, 815, 620, 308

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

Apply this formula for all numbers.

Step1:

LCM(627, 815) = 511005

GCD(627, 815) = ( 627 x 815 ) / 511005

= 627 / 815

= 627

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

Step3:

LCM(1, 308) = 308

GCD(1, 308) = ( 1 x 308 ) / 308

= 1 / 308

= 1

So, Greatest Common Divisor of 627, 815, 620, 308 is 1
