Given numbers are 817, 475, 191, 964

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

Apply this formula for all numbers.

Step1:

LCM(817, 475) = 20425

GCD(817, 475) = ( 817 x 475 ) / 20425

= 817 / 475

= 817

Step2:

LCM(19, 191) = 3629

GCD(19, 191) = ( 19 x 191 ) / 3629

= 19 / 191

= 19

Step3:

LCM(1, 964) = 964

GCD(1, 964) = ( 1 x 964 ) / 964

= 1 / 964

= 1

So, Greatest Common Divisor of 817, 475, 191, 964 is 1
