Given numbers are 401, 306, 640, 681

The list of prime factors of all numbers are

Prime factors of 401 are 401

Prime factors of 306 are 2 x 3 x 3 x 17

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 681 are 3 x 227

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

Given numbers are 401, 306, 640, 681

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

Apply this formula for all numbers.

Step1:

LCM(401, 306) = 122706

GCD(401, 306) = ( 401 x 306 ) / 122706

= 401 / 306

= 401

Step2:

LCM(1, 640) = 640

GCD(1, 640) = ( 1 x 640 ) / 640

= 1 / 640

= 1

Step3:

LCM(1, 681) = 681

GCD(1, 681) = ( 1 x 681 ) / 681

= 1 / 681

= 1

So, Greatest Common Divisor of 401, 306, 640, 681 is 1
