We found the divisors of 129, 190, 30, 658 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 129, 190, 30, 658 is 1.

Therefore, GCD of numbers 129, 190, 30, 658 is 1

Given Input Data is 129, 190, 30, 658

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

Prime Factorization of 129 is 3 x 43

Prime Factorization of 190 is 2 x 5 x 19

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 658 is 2 x 7 x 47

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(129, 190) = 24510

GCD(129, 190) = ( 129 x 190 ) / 24510

GCD(129, 190) = 24510 / 24510

GCD(129, 190) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 30

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

LCM(1, 30) = 30

GCD(1, 30) = ( 1 x 30 ) / 30

GCD(1, 30) = 30 / 30

GCD(1, 30) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 658

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

LCM(1, 658) = 658

GCD(1, 658) = ( 1 x 658 ) / 658

GCD(1, 658) = 658 / 658

GCD(1, 658) = 1

GCD of 129, 190, 30, 658 is 1
