Given numbers are 663, 401, 375, 420

The list of prime factors of all numbers are

Prime factors of 663 are 3 x 13 x 17

Prime factors of 401 are 401

Prime factors of 375 are 3 x 5 x 5 x 5

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

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

Given numbers are 663, 401, 375, 420

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

Apply this formula for all numbers.

Step1:

LCM(663, 401) = 265863

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

= 663 / 401

= 663

Step2:

LCM(1, 375) = 375

GCD(1, 375) = ( 1 x 375 ) / 375

= 1 / 375

= 1

Step3:

LCM(1, 420) = 420

GCD(1, 420) = ( 1 x 420 ) / 420

= 1 / 420

= 1

So, Greatest Common Divisor of 663, 401, 375, 420 is 1
