Given numbers are 411, 645, 731, 211

The list of prime factors of all numbers are

Prime factors of 411 are 3 x 137

Prime factors of 645 are 3 x 5 x 43

Prime factors of 731 are 17 x 43

Prime factors of 211 are 211

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

Given numbers are 411, 645, 731, 211

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

Apply this formula for all numbers.

Step1:

LCM(411, 645) = 88365

GCD(411, 645) = ( 411 x 645 ) / 88365

= 411 / 645

= 411

Step2:

LCM(3, 731) = 2193

GCD(3, 731) = ( 3 x 731 ) / 2193

= 3 / 731

= 3

Step3:

LCM(1, 211) = 211

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

= 1 / 211

= 1

So, Greatest Common Divisor of 411, 645, 731, 211 is 1
