Given numbers are 455, 310, 219, 636

The list of prime factors of all numbers are

Prime factors of 455 are 5 x 7 x 13

Prime factors of 310 are 2 x 5 x 31

Prime factors of 219 are 3 x 73

Prime factors of 636 are 2 x 2 x 3 x 53

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

Given numbers are 455, 310, 219, 636

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

Apply this formula for all numbers.

Step1:

LCM(455, 310) = 28210

GCD(455, 310) = ( 455 x 310 ) / 28210

= 455 / 310

= 455

Step2:

LCM(5, 219) = 1095

GCD(5, 219) = ( 5 x 219 ) / 1095

= 5 / 219

= 5

Step3:

LCM(1, 636) = 636

GCD(1, 636) = ( 1 x 636 ) / 636

= 1 / 636

= 1

So, Greatest Common Divisor of 455, 310, 219, 636 is 1
