Given numbers are 430, 415, 686, 818

The list of prime factors of all numbers are

Prime factors of 430 are 2 x 5 x 43

Prime factors of 415 are 5 x 83

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

Prime factors of 818 are 2 x 409

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

Given numbers are 430, 415, 686, 818

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

Apply this formula for all numbers.

Step1:

LCM(430, 415) = 35690

GCD(430, 415) = ( 430 x 415 ) / 35690

= 430 / 415

= 430

Step2:

LCM(5, 686) = 3430

GCD(5, 686) = ( 5 x 686 ) / 3430

= 5 / 686

= 5

Step3:

LCM(1, 818) = 818

GCD(1, 818) = ( 1 x 818 ) / 818

= 1 / 818

= 1

So, Greatest Common Divisor of 430, 415, 686, 818 is 1
