Given numbers are 680, 686, 770, 811

The list of prime factors of all numbers are

Prime factors of 680 are 2 x 2 x 2 x 5 x 17

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

Prime factors of 770 are 2 x 5 x 7 x 11

Prime factors of 811 are 811

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

Given numbers are 680, 686, 770, 811

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

Apply this formula for all numbers.

Step1:

LCM(680, 686) = 233240

GCD(680, 686) = ( 680 x 686 ) / 233240

= 680 / 686

= 680

Step2:

LCM(2, 770) = 770

GCD(2, 770) = ( 2 x 770 ) / 770

= 2 / 770

= 2

Step3:

LCM(2, 811) = 1622

GCD(2, 811) = ( 2 x 811 ) / 1622

= 2 / 811

= 2

So, Greatest Common Divisor of 680, 686, 770, 811 is 1
