Given numbers are 305, 273, 216, 645

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 273 are 3 x 7 x 13

Prime factors of 216 are 2 x 2 x 2 x 3 x 3 x 3

Prime factors of 645 are 3 x 5 x 43

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

Given numbers are 305, 273, 216, 645

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

Apply this formula for all numbers.

Step1:

LCM(305, 273) = 83265

GCD(305, 273) = ( 305 x 273 ) / 83265

= 305 / 273

= 305

Step2:

LCM(1, 216) = 216

GCD(1, 216) = ( 1 x 216 ) / 216

= 1 / 216

= 1

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 305, 273, 216, 645 is 1
