Given numbers are 402, 580, 311, 904

The list of prime factors of all numbers are

Prime factors of 402 are 2 x 3 x 67

Prime factors of 580 are 2 x 2 x 5 x 29

Prime factors of 311 are 311

Prime factors of 904 are 2 x 2 x 2 x 113

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

Given numbers are 402, 580, 311, 904

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

Apply this formula for all numbers.

Step1:

LCM(402, 580) = 116580

GCD(402, 580) = ( 402 x 580 ) / 116580

= 402 / 580

= 402

Step2:

LCM(2, 311) = 622

GCD(2, 311) = ( 2 x 311 ) / 622

= 2 / 311

= 2

Step3:

LCM(1, 904) = 904

GCD(1, 904) = ( 1 x 904 ) / 904

= 1 / 904

= 1

So, Greatest Common Divisor of 402, 580, 311, 904 is 1
