Given numbers are 680, 120, 561, 331

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 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 561 are 3 x 11 x 17

Prime factors of 331 are 331

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

Given numbers are 680, 120, 561, 331

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

Apply this formula for all numbers.

Step1:

LCM(680, 120) = 2040

GCD(680, 120) = ( 680 x 120 ) / 2040

= 680 / 120

= 680

Step2:

LCM(40, 561) = 22440

GCD(40, 561) = ( 40 x 561 ) / 22440

= 40 / 561

= 40

Step3:

LCM(1, 331) = 331

GCD(1, 331) = ( 1 x 331 ) / 331

= 1 / 331

= 1

So, Greatest Common Divisor of 680, 120, 561, 331 is 1
