Given numbers are 212, 617, 342, 420

The list of prime factors of all numbers are

Prime factors of 212 are 2 x 2 x 53

Prime factors of 617 are 617

Prime factors of 342 are 2 x 3 x 3 x 19

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

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

Given numbers are 212, 617, 342, 420

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

Apply this formula for all numbers.

Step1:

LCM(212, 617) = 130804

GCD(212, 617) = ( 212 x 617 ) / 130804

= 212 / 617

= 212

Step2:

LCM(1, 342) = 342

GCD(1, 342) = ( 1 x 342 ) / 342

= 1 / 342

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 212, 617, 342, 420 is 1
