Given numbers are 618, 195, 803, 855

The list of prime factors of all numbers are

Prime factors of 618 are 2 x 3 x 103

Prime factors of 195 are 3 x 5 x 13

Prime factors of 803 are 11 x 73

Prime factors of 855 are 3 x 3 x 5 x 19

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

Given numbers are 618, 195, 803, 855

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

Apply this formula for all numbers.

Step1:

LCM(618, 195) = 40170

GCD(618, 195) = ( 618 x 195 ) / 40170

= 618 / 195

= 618

Step2:

LCM(3, 803) = 2409

GCD(3, 803) = ( 3 x 803 ) / 2409

= 3 / 803

= 3

Step3:

LCM(1, 855) = 855

GCD(1, 855) = ( 1 x 855 ) / 855

= 1 / 855

= 1

So, Greatest Common Divisor of 618, 195, 803, 855 is 1
