Given numbers are 215, 387, 205, 273

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 387 are 3 x 3 x 43

Prime factors of 205 are 5 x 41

Prime factors of 273 are 3 x 7 x 13

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

Given numbers are 215, 387, 205, 273

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

Apply this formula for all numbers.

Step1:

LCM(215, 387) = 1935

GCD(215, 387) = ( 215 x 387 ) / 1935

= 215 / 387

= 215

Step2:

LCM(43, 205) = 8815

GCD(43, 205) = ( 43 x 205 ) / 8815

= 43 / 205

= 43

Step3:

LCM(1, 273) = 273

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

= 1 / 273

= 1

So, Greatest Common Divisor of 215, 387, 205, 273 is 1
