Given numbers are 689, 628, 479, 188

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

Apply this formula for all numbers.

Step1:

LCM(689, 628) = 432692

GCD(689, 628) = ( 689 x 628 ) / 432692

= 689 / 628

= 689

Step2:

LCM(1, 479) = 479

GCD(1, 479) = ( 1 x 479 ) / 479

= 1 / 479

= 1

Step3:

LCM(1, 188) = 188

GCD(1, 188) = ( 1 x 188 ) / 188

= 1 / 188

= 1

So, Greatest Common Divisor of 689, 628, 479, 188 is 1
