Given numbers are 390, 487, 224, 211

The list of prime factors of all numbers are

Prime factors of 390 are 2 x 3 x 5 x 13

Prime factors of 487 are 487

Prime factors of 224 are 2 x 2 x 2 x 2 x 2 x 7

Prime factors of 211 are 211

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

Given numbers are 390, 487, 224, 211

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

Apply this formula for all numbers.

Step1:

LCM(390, 487) = 189930

GCD(390, 487) = ( 390 x 487 ) / 189930

= 390 / 487

= 390

Step2:

LCM(1, 224) = 224

GCD(1, 224) = ( 1 x 224 ) / 224

= 1 / 224

= 1

Step3:

LCM(1, 211) = 211

GCD(1, 211) = ( 1 x 211 ) / 211

= 1 / 211

= 1

So, Greatest Common Divisor of 390, 487, 224, 211 is 1
