Given numbers are 171, 608, 718, 645

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

Apply this formula for all numbers.

Step1:

LCM(171, 608) = 5472

GCD(171, 608) = ( 171 x 608 ) / 5472

= 171 / 608

= 171

Step2:

LCM(19, 718) = 13642

GCD(19, 718) = ( 19 x 718 ) / 13642

= 19 / 718

= 19

Step3:

LCM(1, 645) = 645

GCD(1, 645) = ( 1 x 645 ) / 645

= 1 / 645

= 1

So, Greatest Common Divisor of 171, 608, 718, 645 is 1
