Given numbers are 821, 393, 527, 611

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

Apply this formula for all numbers.

Step1:

LCM(821, 393) = 322653

GCD(821, 393) = ( 821 x 393 ) / 322653

= 821 / 393

= 821

Step2:

LCM(1, 527) = 527

GCD(1, 527) = ( 1 x 527 ) / 527

= 1 / 527

= 1

Step3:

LCM(1, 611) = 611

GCD(1, 611) = ( 1 x 611 ) / 611

= 1 / 611

= 1

So, Greatest Common Divisor of 821, 393, 527, 611 is 1
