Given numbers are 667, 920, 388, 643

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

Apply this formula for all numbers.

Step1:

LCM(667, 920) = 26680

GCD(667, 920) = ( 667 x 920 ) / 26680

= 667 / 920

= 667

Step2:

LCM(23, 388) = 8924

GCD(23, 388) = ( 23 x 388 ) / 8924

= 23 / 388

= 23

Step3:

LCM(1, 643) = 643

GCD(1, 643) = ( 1 x 643 ) / 643

= 1 / 643

= 1

So, Greatest Common Divisor of 667, 920, 388, 643 is 1
