Given numbers are 667, 353, 620, 680

The list of prime factors of all numbers are

Prime factors of 667 are 23 x 29

Prime factors of 353 are 353

Prime factors of 620 are 2 x 2 x 5 x 31

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

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

Given numbers are 667, 353, 620, 680

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

Apply this formula for all numbers.

Step1:

LCM(667, 353) = 235451

GCD(667, 353) = ( 667 x 353 ) / 235451

= 667 / 353

= 667

Step2:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

Step3:

LCM(1, 680) = 680

GCD(1, 680) = ( 1 x 680 ) / 680

= 1 / 680

= 1

So, Greatest Common Divisor of 667, 353, 620, 680 is 1
