Given numbers are 308, 866, 647, 628

The list of prime factors of all numbers are

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

Prime factors of 866 are 2 x 433

Prime factors of 647 are 647

Prime factors of 628 are 2 x 2 x 157

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

Given numbers are 308, 866, 647, 628

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

Apply this formula for all numbers.

Step1:

LCM(308, 866) = 133364

GCD(308, 866) = ( 308 x 866 ) / 133364

= 308 / 866

= 308

Step2:

LCM(2, 647) = 1294

GCD(2, 647) = ( 2 x 647 ) / 1294

= 2 / 647

= 2

Step3:

LCM(1, 628) = 628

GCD(1, 628) = ( 1 x 628 ) / 628

= 1 / 628

= 1

So, Greatest Common Divisor of 308, 866, 647, 628 is 1
