Given numbers are 618, 628, 235, 664

The list of prime factors of all numbers are

Prime factors of 618 are 2 x 3 x 103

Prime factors of 628 are 2 x 2 x 157

Prime factors of 235 are 5 x 47

Prime factors of 664 are 2 x 2 x 2 x 83

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

Given numbers are 618, 628, 235, 664

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

Apply this formula for all numbers.

Step1:

LCM(618, 628) = 194052

GCD(618, 628) = ( 618 x 628 ) / 194052

= 618 / 628

= 618

Step2:

LCM(2, 235) = 470

GCD(2, 235) = ( 2 x 235 ) / 470

= 2 / 235

= 2

Step3:

LCM(1, 664) = 664

GCD(1, 664) = ( 1 x 664 ) / 664

= 1 / 664

= 1

So, Greatest Common Divisor of 618, 628, 235, 664 is 1
