Given numbers are 215, 601, 273, 420

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 601 are 601

Prime factors of 273 are 3 x 7 x 13

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 215, 601, 273, 420

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

Apply this formula for all numbers.

Step1:

LCM(215, 601) = 129215

GCD(215, 601) = ( 215 x 601 ) / 129215

= 215 / 601

= 215

Step2:

LCM(1, 273) = 273

GCD(1, 273) = ( 1 x 273 ) / 273

= 1 / 273

= 1

Step3:

LCM(1, 420) = 420

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

= 1 / 420

= 1

So, Greatest Common Divisor of 215, 601, 273, 420 is 1
