Given numbers are 168, 621, 393, 919

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

Apply this formula for all numbers.

Step1:

LCM(168, 621) = 34776

GCD(168, 621) = ( 168 x 621 ) / 34776

= 168 / 621

= 168

Step2:

LCM(3, 393) = 393

GCD(3, 393) = ( 3 x 393 ) / 393

= 3 / 393

= 3

Step3:

LCM(3, 919) = 2757

GCD(3, 919) = ( 3 x 919 ) / 2757

= 3 / 919

= 3

So, Greatest Common Divisor of 168, 621, 393, 919 is 1
