Given numbers are 305, 121, 472, 871

The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 121 are 11 x 11

Prime factors of 472 are 2 x 2 x 2 x 59

Prime factors of 871 are 13 x 67

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

Given numbers are 305, 121, 472, 871

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

Apply this formula for all numbers.

Step1:

LCM(305, 121) = 36905

GCD(305, 121) = ( 305 x 121 ) / 36905

= 305 / 121

= 305

Step2:

LCM(1, 472) = 472

GCD(1, 472) = ( 1 x 472 ) / 472

= 1 / 472

= 1

Step3:

LCM(1, 871) = 871

GCD(1, 871) = ( 1 x 871 ) / 871

= 1 / 871

= 1

So, Greatest Common Divisor of 305, 121, 472, 871 is 1
