Given numbers are 817, 865, 211, 623

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

Apply this formula for all numbers.

Step1:

LCM(817, 865) = 706705

GCD(817, 865) = ( 817 x 865 ) / 706705

= 817 / 865

= 817

Step2:

LCM(1, 211) = 211

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

= 1 / 211

= 1

Step3:

LCM(1, 623) = 623

GCD(1, 623) = ( 1 x 623 ) / 623

= 1 / 623

= 1

So, Greatest Common Divisor of 817, 865, 211, 623 is 1
