Given numbers are 171, 680, 822, 686

The list of prime factors of all numbers are

Prime factors of 171 are 3 x 3 x 19

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

Prime factors of 822 are 2 x 3 x 137

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 171, 680, 822, 686

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

Apply this formula for all numbers.

Step1:

LCM(171, 680) = 116280

GCD(171, 680) = ( 171 x 680 ) / 116280

= 171 / 680

= 171

Step2:

LCM(1, 822) = 822

GCD(1, 822) = ( 1 x 822 ) / 822

= 1 / 822

= 1

Step3:

LCM(1, 686) = 686

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

= 1 / 686

= 1

So, Greatest Common Divisor of 171, 680, 822, 686 is 1
