Given numbers are 681, 664, 421, 719

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

Apply this formula for all numbers.

Step1:

LCM(681, 664) = 452184

GCD(681, 664) = ( 681 x 664 ) / 452184

= 681 / 664

= 681

Step2:

LCM(1, 421) = 421

GCD(1, 421) = ( 1 x 421 ) / 421

= 1 / 421

= 1

Step3:

LCM(1, 719) = 719

GCD(1, 719) = ( 1 x 719 ) / 719

= 1 / 719

= 1

So, Greatest Common Divisor of 681, 664, 421, 719 is 1
