Given numbers are 420, 595, 198, 198

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 595 are 5 x 7 x 17

Prime factors of 198 are 2 x 3 x 3 x 11

Prime factors of 198 are 2 x 3 x 3 x 11

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

Given numbers are 420, 595, 198, 198

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

Apply this formula for all numbers.

Step1:

LCM(420, 595) = 7140

GCD(420, 595) = ( 420 x 595 ) / 7140

= 420 / 595

= 420

Step2:

LCM(35, 198) = 6930

GCD(35, 198) = ( 35 x 198 ) / 6930

= 35 / 198

= 35

Step3:

LCM(1, 198) = 198

GCD(1, 198) = ( 1 x 198 ) / 198

= 1 / 198

= 1

So, Greatest Common Divisor of 420, 595, 198, 198 is 1
