Given numbers are 720, 386, 422, 211

The list of prime factors of all numbers are

Prime factors of 720 are 2 x 2 x 2 x 2 x 3 x 3 x 5

Prime factors of 386 are 2 x 193

Prime factors of 422 are 2 x 211

Prime factors of 211 are 211

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

Given numbers are 720, 386, 422, 211

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

Apply this formula for all numbers.

Step1:

LCM(720, 386) = 138960

GCD(720, 386) = ( 720 x 386 ) / 138960

= 720 / 386

= 720

Step2:

LCM(2, 422) = 422

GCD(2, 422) = ( 2 x 422 ) / 422

= 2 / 422

= 2

Step3:

LCM(2, 211) = 422

GCD(2, 211) = ( 2 x 211 ) / 422

= 2 / 211

= 2

So, Greatest Common Divisor of 720, 386, 422, 211 is 1
