Given numbers are 171, 431, 817, 731

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

Apply this formula for all numbers.

Step1:

LCM(171, 431) = 73701

GCD(171, 431) = ( 171 x 431 ) / 73701

= 171 / 431

= 171

Step2:

LCM(1, 817) = 817

GCD(1, 817) = ( 1 x 817 ) / 817

= 1 / 817

= 1

Step3:

LCM(1, 731) = 731

GCD(1, 731) = ( 1 x 731 ) / 731

= 1 / 731

= 1

So, Greatest Common Divisor of 171, 431, 817, 731 is 1
