Given numbers are 817, 165, 427, 503

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

Apply this formula for all numbers.

Step1:

LCM(817, 165) = 134805

GCD(817, 165) = ( 817 x 165 ) / 134805

= 817 / 165

= 817

Step2:

LCM(1, 427) = 427

GCD(1, 427) = ( 1 x 427 ) / 427

= 1 / 427

= 1

Step3:

LCM(1, 503) = 503

GCD(1, 503) = ( 1 x 503 ) / 503

= 1 / 503

= 1

So, Greatest Common Divisor of 817, 165, 427, 503 is 1
