Given numbers are 420, 518, 720, 211

The list of prime factors of all numbers are

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 518 are 2 x 7 x 37

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

Prime factors of 211 are 211

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

Given numbers are 420, 518, 720, 211

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

Apply this formula for all numbers.

Step1:

LCM(420, 518) = 15540

GCD(420, 518) = ( 420 x 518 ) / 15540

= 420 / 518

= 420

Step2:

LCM(14, 720) = 5040

GCD(14, 720) = ( 14 x 720 ) / 5040

= 14 / 720

= 14

Step3:

LCM(2, 211) = 422

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

= 2 / 211

= 2

So, Greatest Common Divisor of 420, 518, 720, 211 is 1
