Given numbers are 681, 420, 705, 866

The list of prime factors of all numbers are

Prime factors of 681 are 3 x 227

Prime factors of 420 are 2 x 2 x 3 x 5 x 7

Prime factors of 705 are 3 x 5 x 47

Prime factors of 866 are 2 x 433

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 681, 420, 705, 866

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

Apply this formula for all numbers.

Step1:

LCM(681, 420) = 95340

GCD(681, 420) = ( 681 x 420 ) / 95340

= 681 / 420

= 681

Step2:

LCM(3, 705) = 705

GCD(3, 705) = ( 3 x 705 ) / 705

= 3 / 705

= 3

Step3:

LCM(3, 866) = 2598

GCD(3, 866) = ( 3 x 866 ) / 2598

= 3 / 866

= 3

So, Greatest Common Divisor of 681, 420, 705, 866 is 1
