So the Greatest Common Divisior 321, 790, 402, 671 is 1.

Therefore, GCD of numbers 321, 790, 402, 671 is 1

Given Input Data is 321, 790, 402, 671

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 321 is 3 x 107

Prime Factorization of 790 is 2 x 5 x 79

Prime Factorization of 402 is 2 x 3 x 67

Prime Factorization of 671 is 11 x 61

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

Step1:

Let's calculate the GCD of first two numbers

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

LCM(321, 790) = 253590

GCD(321, 790) = ( 321 x 790 ) / 253590

GCD(321, 790) = 253590 / 253590

GCD(321, 790) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 402

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

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

GCD(1, 402) = 402 / 402

GCD(1, 402) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 671

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

LCM(1, 671) = 671

GCD(1, 671) = ( 1 x 671 ) / 671

GCD(1, 671) = 671 / 671

GCD(1, 671) = 1

GCD of 321, 790, 402, 671 is 1
