Given numbers are 402, 311, 380, 815

The list of prime factors of all numbers are

Prime factors of 402 are 2 x 3 x 67

Prime factors of 311 are 311

Prime factors of 380 are 2 x 2 x 5 x 19

Prime factors of 815 are 5 x 163

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

Given numbers are 402, 311, 380, 815

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

Apply this formula for all numbers.

Step1:

LCM(402, 311) = 125022

GCD(402, 311) = ( 402 x 311 ) / 125022

= 402 / 311

= 402

Step2:

LCM(1, 380) = 380

GCD(1, 380) = ( 1 x 380 ) / 380

= 1 / 380

= 1

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 402, 311, 380, 815 is 1
