We found the divisors of 606, 643, 42, 402 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 606, 643, 42, 402 is 1.

Therefore, GCD of numbers 606, 643, 42, 402 is 1

Given Input Data is 606, 643, 42, 402

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

Prime Factorization of 606 is 2 x 3 x 101

Prime Factorization of 643 is 643

Prime Factorization of 42 is 2 x 3 x 7

Prime Factorization of 402 is 2 x 3 x 67

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(606, 643) = 389658

GCD(606, 643) = ( 606 x 643 ) / 389658

GCD(606, 643) = 389658 / 389658

GCD(606, 643) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 42

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

LCM(1, 42) = 42

GCD(1, 42) = ( 1 x 42 ) / 42

GCD(1, 42) = 42 / 42

GCD(1, 42) = 1

Step3:

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

GCD of 606, 643, 42, 402 is 1
