Given numbers are 215, 481, 645, 550

The list of prime factors of all numbers are

Prime factors of 215 are 5 x 43

Prime factors of 481 are 13 x 37

Prime factors of 645 are 3 x 5 x 43

Prime factors of 550 are 2 x 5 x 5 x 11

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

Given numbers are 215, 481, 645, 550

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

Apply this formula for all numbers.

Step1:

LCM(215, 481) = 103415

GCD(215, 481) = ( 215 x 481 ) / 103415

= 215 / 481

= 215

Step2:

LCM(1, 645) = 645

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

= 1 / 645

= 1

Step3:

LCM(1, 550) = 550

GCD(1, 550) = ( 1 x 550 ) / 550

= 1 / 550

= 1

So, Greatest Common Divisor of 215, 481, 645, 550 is 1
