Given numbers are 168, 517, 639, 930

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

Apply this formula for all numbers.

Step1:

LCM(168, 517) = 86856

GCD(168, 517) = ( 168 x 517 ) / 86856

= 168 / 517

= 168

Step2:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

Step3:

LCM(1, 930) = 930

GCD(1, 930) = ( 1 x 930 ) / 930

= 1 / 930

= 1

So, Greatest Common Divisor of 168, 517, 639, 930 is 1
