Given numbers are 310, 428, 455, 211

The list of prime factors of all numbers are

Prime factors of 310 are 2 x 5 x 31

Prime factors of 428 are 2 x 2 x 107

Prime factors of 455 are 5 x 7 x 13

Prime factors of 211 are 211

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

Given numbers are 310, 428, 455, 211

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

Apply this formula for all numbers.

Step1:

LCM(310, 428) = 66340

GCD(310, 428) = ( 310 x 428 ) / 66340

= 310 / 428

= 310

Step2:

LCM(2, 455) = 910

GCD(2, 455) = ( 2 x 455 ) / 910

= 2 / 455

= 2

Step3:

LCM(1, 211) = 211

GCD(1, 211) = ( 1 x 211 ) / 211

= 1 / 211

= 1

So, Greatest Common Divisor of 310, 428, 455, 211 is 1
