Given numbers are 401, 663, 314, 221

The list of prime factors of all numbers are

Prime factors of 401 are 401

Prime factors of 663 are 3 x 13 x 17

Prime factors of 314 are 2 x 157

Prime factors of 221 are 13 x 17

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

Given numbers are 401, 663, 314, 221

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

Apply this formula for all numbers.

Step1:

LCM(401, 663) = 265863

GCD(401, 663) = ( 401 x 663 ) / 265863

= 401 / 663

= 401

Step2:

LCM(1, 314) = 314

GCD(1, 314) = ( 1 x 314 ) / 314

= 1 / 314

= 1

Step3:

LCM(1, 221) = 221

GCD(1, 221) = ( 1 x 221 ) / 221

= 1 / 221

= 1

So, Greatest Common Divisor of 401, 663, 314, 221 is 1
