Given numbers are 172, 494, 198, 817

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

Apply this formula for all numbers.

Step1:

LCM(172, 494) = 42484

GCD(172, 494) = ( 172 x 494 ) / 42484

= 172 / 494

= 172

Step2:

LCM(2, 198) = 198

GCD(2, 198) = ( 2 x 198 ) / 198

= 2 / 198

= 2

Step3:

LCM(2, 817) = 1634

GCD(2, 817) = ( 2 x 817 ) / 1634

= 2 / 817

= 2

So, Greatest Common Divisor of 172, 494, 198, 817 is 1
