Given numbers are 630, 420, 401, 659

The list of prime factors of all numbers are

Prime factors of 630 are 2 x 3 x 3 x 5 x 7

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

Prime factors of 401 are 401

Prime factors of 659 are 659

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

Given numbers are 630, 420, 401, 659

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

Apply this formula for all numbers.

Step1:

LCM(630, 420) = 1260

GCD(630, 420) = ( 630 x 420 ) / 1260

= 630 / 420

= 630

Step2:

LCM(210, 401) = 84210

GCD(210, 401) = ( 210 x 401 ) / 84210

= 210 / 401

= 210

Step3:

LCM(1, 659) = 659

GCD(1, 659) = ( 1 x 659 ) / 659

= 1 / 659

= 1

So, Greatest Common Divisor of 630, 420, 401, 659 is 1
