Given numbers are 401, 519, 691, 660

The list of prime factors of all numbers are

Prime factors of 401 are 401

Prime factors of 519 are 3 x 173

Prime factors of 691 are 691

Prime factors of 660 are 2 x 2 x 3 x 5 x 11

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

Given numbers are 401, 519, 691, 660

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

Apply this formula for all numbers.

Step1:

LCM(401, 519) = 208119

GCD(401, 519) = ( 401 x 519 ) / 208119

= 401 / 519

= 401

Step2:

LCM(1, 691) = 691

GCD(1, 691) = ( 1 x 691 ) / 691

= 1 / 691

= 1

Step3:

LCM(1, 660) = 660

GCD(1, 660) = ( 1 x 660 ) / 660

= 1 / 660

= 1

So, Greatest Common Divisor of 401, 519, 691, 660 is 1
