The list of prime factors of all numbers are

Prime factors of 305 are 5 x 61

Prime factors of 775 are 5 x 5 x 31

Prime factors of 921 are 3 x 307

Prime factors of 412 are 2 x 2 x 103

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

Given numbers are 305, 775, 921, 412

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

Apply this formula for all numbers.

Step1:

LCM(305, 775) = 47275

GCD(305, 775) = ( 305 x 775 ) / 47275

= 305 / 775

= 305

Step2:

LCM(5, 921) = 4605

GCD(5, 921) = ( 5 x 921 ) / 4605

= 5 / 921

= 5

Step3:

LCM(1, 412) = 412

GCD(1, 412) = ( 1 x 412 ) / 412

= 1 / 412

= 1

So, Greatest Common Divisor of 305, 775, 921, 412 is 1
