Given numbers are 449, 896, 863, 721

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

Apply this formula for all numbers.

Step1:

LCM(449, 896) = 402304

GCD(449, 896) = ( 449 x 896 ) / 402304

= 449 / 896

= 449

Step2:

LCM(1, 863) = 863

GCD(1, 863) = ( 1 x 863 ) / 863

= 1 / 863

= 1

Step3:

LCM(1, 721) = 721

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

= 1 / 721

= 1

So, Greatest Common Divisor of 449, 896, 863, 721 is 1
