Given numbers are 393, 405, 931, 211

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

Apply this formula for all numbers.

Step1:

LCM(393, 405) = 53055

GCD(393, 405) = ( 393 x 405 ) / 53055

= 393 / 405

= 393

Step2:

LCM(3, 931) = 2793

GCD(3, 931) = ( 3 x 931 ) / 2793

= 3 / 931

= 3

Step3:

LCM(1, 211) = 211

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

= 1 / 211

= 1

So, Greatest Common Divisor of 393, 405, 931, 211 is 1
