Given numbers are 686, 765, 784, 818

The list of prime factors of all numbers are

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

Prime factors of 765 are 3 x 3 x 5 x 17

Prime factors of 784 are 2 x 2 x 2 x 2 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 686, 765, 784, 818

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

Apply this formula for all numbers.

Step1:

LCM(686, 765) = 524790

GCD(686, 765) = ( 686 x 765 ) / 524790

= 686 / 765

= 686

Step2:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

Step3:

LCM(1, 818) = 818

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

= 1 / 818

= 1

So, Greatest Common Divisor of 686, 765, 784, 818 is 1
