Given numbers are 171, 688, 485

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

Apply this formula for all numbers.

Step1:

LCM(171, 688) = 117648

GCD(171, 688) = ( 171 x 688 ) / 117648

= 171 / 688

= 171

Step2:

LCM(1, 485) = 485

GCD(1, 485) = ( 1 x 485 ) / 485

= 1 / 485

= 1

So, Greatest Common Divisor of 171, 688, 485 is 1
