Given numbers are 644, 315, 211, 338

The list of prime factors of all numbers are

Prime factors of 644 are 2 x 2 x 7 x 23

Prime factors of 315 are 3 x 3 x 5 x 7

Prime factors of 211 are 211

Prime factors of 338 are 2 x 13 x 13

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

Given numbers are 644, 315, 211, 338

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

Apply this formula for all numbers.

Step1:

LCM(644, 315) = 28980

GCD(644, 315) = ( 644 x 315 ) / 28980

= 644 / 315

= 644

Step2:

LCM(7, 211) = 1477

GCD(7, 211) = ( 7 x 211 ) / 1477

= 7 / 211

= 7

Step3:

LCM(1, 338) = 338

GCD(1, 338) = ( 1 x 338 ) / 338

= 1 / 338

= 1

So, Greatest Common Divisor of 644, 315, 211, 338 is 1
