Given numbers are 721, 584, 843, 449

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

Apply this formula for all numbers.

Step1:

LCM(721, 584) = 421064

GCD(721, 584) = ( 721 x 584 ) / 421064

= 721 / 584

= 721

Step2:

LCM(1, 843) = 843

GCD(1, 843) = ( 1 x 843 ) / 843

= 1 / 843

= 1

Step3:

LCM(1, 449) = 449

GCD(1, 449) = ( 1 x 449 ) / 449

= 1 / 449

= 1

So, Greatest Common Divisor of 721, 584, 843, 449 is 1
