Given numbers are 206, 417, 310, 355

The list of prime factors of all numbers are

Prime factors of 206 are 2 x 103

Prime factors of 417 are 3 x 139

Prime factors of 310 are 2 x 5 x 31

Prime factors of 355 are 5 x 71

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

Given numbers are 206, 417, 310, 355

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

Apply this formula for all numbers.

Step1:

LCM(206, 417) = 85902

GCD(206, 417) = ( 206 x 417 ) / 85902

= 206 / 417

= 206

Step2:

LCM(1, 310) = 310

GCD(1, 310) = ( 1 x 310 ) / 310

= 1 / 310

= 1

Step3:

LCM(1, 355) = 355

GCD(1, 355) = ( 1 x 355 ) / 355

= 1 / 355

= 1

So, Greatest Common Divisor of 206, 417, 310, 355 is 1
