Given numbers are 721, 689, 419, 444

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

Apply this formula for all numbers.

Step1:

LCM(721, 689) = 496769

GCD(721, 689) = ( 721 x 689 ) / 496769

= 721 / 689

= 721

Step2:

LCM(1, 419) = 419

GCD(1, 419) = ( 1 x 419 ) / 419

= 1 / 419

= 1

Step3:

LCM(1, 444) = 444

GCD(1, 444) = ( 1 x 444 ) / 444

= 1 / 444

= 1

So, Greatest Common Divisor of 721, 689, 419, 444 is 1
