Given numbers are 618, 388, 517, 781

The list of prime factors of all numbers are

Prime factors of 618 are 2 x 3 x 103

Prime factors of 388 are 2 x 2 x 97

Prime factors of 517 are 11 x 47

Prime factors of 781 are 11 x 71

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

Given numbers are 618, 388, 517, 781

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

Apply this formula for all numbers.

Step1:

LCM(618, 388) = 119892

GCD(618, 388) = ( 618 x 388 ) / 119892

= 618 / 388

= 618

Step2:

LCM(2, 517) = 1034

GCD(2, 517) = ( 2 x 517 ) / 1034

= 2 / 517

= 2

Step3:

LCM(1, 781) = 781

GCD(1, 781) = ( 1 x 781 ) / 781

= 1 / 781

= 1

So, Greatest Common Divisor of 618, 388, 517, 781 is 1
