Given numbers are 138, 457, 270, 401

The list of prime factors of all numbers are

Prime factors of 138 are 2 x 3 x 23

Prime factors of 457 are 457

Prime factors of 270 are 2 x 3 x 3 x 3 x 5

Prime factors of 401 are 401

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

Given numbers are 138, 457, 270, 401

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

Apply this formula for all numbers.

Step1:

LCM(138, 457) = 63066

GCD(138, 457) = ( 138 x 457 ) / 63066

= 138 / 457

= 138

Step2:

LCM(1, 270) = 270

GCD(1, 270) = ( 1 x 270 ) / 270

= 1 / 270

= 1

Step3:

LCM(1, 401) = 401

GCD(1, 401) = ( 1 x 401 ) / 401

= 1 / 401

= 1

So, Greatest Common Divisor of 138, 457, 270, 401 is 1
