Given numbers are 618, 804, 210, 685

The list of prime factors of all numbers are

Prime factors of 618 are 2 x 3 x 103

Prime factors of 804 are 2 x 2 x 3 x 67

Prime factors of 210 are 2 x 3 x 5 x 7

Prime factors of 685 are 5 x 137

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

Given numbers are 618, 804, 210, 685

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

Apply this formula for all numbers.

Step1:

LCM(618, 804) = 82812

GCD(618, 804) = ( 618 x 804 ) / 82812

= 618 / 804

= 618

Step2:

LCM(6, 210) = 210

GCD(6, 210) = ( 6 x 210 ) / 210

= 6 / 210

= 6

Step3:

LCM(6, 685) = 4110

GCD(6, 685) = ( 6 x 685 ) / 4110

= 6 / 685

= 6

So, Greatest Common Divisor of 618, 804, 210, 685 is 1
