Given numbers are 681, 406, 428, 631

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

Apply this formula for all numbers.

Step1:

LCM(681, 406) = 276486

GCD(681, 406) = ( 681 x 406 ) / 276486

= 681 / 406

= 681

Step2:

LCM(1, 428) = 428

GCD(1, 428) = ( 1 x 428 ) / 428

= 1 / 428

= 1

Step3:

LCM(1, 631) = 631

GCD(1, 631) = ( 1 x 631 ) / 631

= 1 / 631

= 1

So, Greatest Common Divisor of 681, 406, 428, 631 is 1
