Given numbers are 628, 867, 721, 239

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

Apply this formula for all numbers.

Step1:

LCM(628, 867) = 544476

GCD(628, 867) = ( 628 x 867 ) / 544476

= 628 / 867

= 628

Step2:

LCM(1, 721) = 721

GCD(1, 721) = ( 1 x 721 ) / 721

= 1 / 721

= 1

Step3:

LCM(1, 239) = 239

GCD(1, 239) = ( 1 x 239 ) / 239

= 1 / 239

= 1

So, Greatest Common Divisor of 628, 867, 721, 239 is 1
