Given numbers are 618, 684, 689, 669

The list of prime factors of all numbers are

Prime factors of 618 are 2 x 3 x 103

Prime factors of 684 are 2 x 2 x 3 x 3 x 19

Prime factors of 689 are 13 x 53

Prime factors of 669 are 3 x 223

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

Given numbers are 618, 684, 689, 669

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

Apply this formula for all numbers.

Step1:

LCM(618, 684) = 70452

GCD(618, 684) = ( 618 x 684 ) / 70452

= 618 / 684

= 618

Step2:

LCM(6, 689) = 4134

GCD(6, 689) = ( 6 x 689 ) / 4134

= 6 / 689

= 6

Step3:

LCM(1, 669) = 669

GCD(1, 669) = ( 1 x 669 ) / 669

= 1 / 669

= 1

So, Greatest Common Divisor of 618, 684, 689, 669 is 1
