Given numbers are 305, 651, 311, 427

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 651 are 3 x 7 x 31

Prime factors of 311 are 311

Prime factors of 427 are 7 x 61

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

Given numbers are 305, 651, 311, 427

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

Apply this formula for all numbers.

Step1:

LCM(305, 651) = 198555

GCD(305, 651) = ( 305 x 651 ) / 198555

= 305 / 651

= 305

Step2:

LCM(1, 311) = 311

GCD(1, 311) = ( 1 x 311 ) / 311

= 1 / 311

= 1

Step3:

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

= 1 / 427

= 1

So, Greatest Common Divisor of 305, 651, 311, 427 is 1
