Given numbers are 401, 408, 299, 620

The list of prime factors of all numbers are

Prime factors of 401 are 401

Prime factors of 408 are 2 x 2 x 2 x 3 x 17

Prime factors of 299 are 13 x 23

Prime factors of 620 are 2 x 2 x 5 x 31

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

Given numbers are 401, 408, 299, 620

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

Apply this formula for all numbers.

Step1:

LCM(401, 408) = 163608

GCD(401, 408) = ( 401 x 408 ) / 163608

= 401 / 408

= 401

Step2:

LCM(1, 299) = 299

GCD(1, 299) = ( 1 x 299 ) / 299

= 1 / 299

= 1

Step3:

LCM(1, 620) = 620

GCD(1, 620) = ( 1 x 620 ) / 620

= 1 / 620

= 1

So, Greatest Common Divisor of 401, 408, 299, 620 is 1
