Given numbers are 509, 611, 653, 805

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

Apply this formula for all numbers.

Step1:

LCM(509, 611) = 310999

GCD(509, 611) = ( 509 x 611 ) / 310999

= 509 / 611

= 509

Step2:

LCM(1, 653) = 653

GCD(1, 653) = ( 1 x 653 ) / 653

= 1 / 653

= 1

Step3:

LCM(1, 805) = 805

GCD(1, 805) = ( 1 x 805 ) / 805

= 1 / 805

= 1

So, Greatest Common Divisor of 509, 611, 653, 805 is 1
