Given numbers are 686, 328, 120, 613

The list of prime factors of all numbers are

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

Prime factors of 328 are 2 x 2 x 2 x 41

Prime factors of 120 are 2 x 2 x 2 x 3 x 5

Prime factors of 613 are 613

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

Given numbers are 686, 328, 120, 613

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

Apply this formula for all numbers.

Step1:

LCM(686, 328) = 112504

GCD(686, 328) = ( 686 x 328 ) / 112504

= 686 / 328

= 686

Step2:

LCM(2, 120) = 120

GCD(2, 120) = ( 2 x 120 ) / 120

= 2 / 120

= 2

Step3:

LCM(2, 613) = 1226

GCD(2, 613) = ( 2 x 613 ) / 1226

= 2 / 613

= 2

So, Greatest Common Divisor of 686, 328, 120, 613 is 1
