Given numbers are 668, 388, 640, 919

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

Apply this formula for all numbers.

Step1:

LCM(668, 388) = 64796

GCD(668, 388) = ( 668 x 388 ) / 64796

= 668 / 388

= 668

Step2:

LCM(4, 640) = 640

GCD(4, 640) = ( 4 x 640 ) / 640

= 4 / 640

= 4

Step3:

LCM(4, 919) = 3676

GCD(4, 919) = ( 4 x 919 ) / 3676

= 4 / 919

= 4

So, Greatest Common Divisor of 668, 388, 640, 919 is 1
