Given numbers are 681, 339, 445, 478

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

Apply this formula for all numbers.

Step1:

LCM(681, 339) = 76953

GCD(681, 339) = ( 681 x 339 ) / 76953

= 681 / 339

= 681

Step2:

LCM(3, 445) = 1335

GCD(3, 445) = ( 3 x 445 ) / 1335

= 3 / 445

= 3

Step3:

LCM(1, 478) = 478

GCD(1, 478) = ( 1 x 478 ) / 478

= 1 / 478

= 1

So, Greatest Common Divisor of 681, 339, 445, 478 is 1
