Given numbers are 955, 498, 420, 686

The list of prime factors of all numbers are

Prime factors of 955 are 5 x 191

Prime factors of 498 are 2 x 3 x 83

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 686 are 2 x 7 x 7 x 7

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

Given numbers are 955, 498, 420, 686

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

Apply this formula for all numbers.

Step1:

LCM(955, 498) = 475590

GCD(955, 498) = ( 955 x 498 ) / 475590

= 955 / 498

= 955

Step2:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

Step3:

LCM(1, 686) = 686

GCD(1, 686) = ( 1 x 686 ) / 686

= 1 / 686

= 1

So, Greatest Common Divisor of 955, 498, 420, 686 is 1
