We found the divisors of 38, 12, 49 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 38, 12, 49 is 1.

Therefore, GCD of numbers 38, 12, 49 is 1

Given Input Data is 38, 12, 49

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

Prime Factorization of 38 is 2 x 19

Prime Factorization of 12 is 2 x 2 x 3

Prime Factorization of 49 is 7 x 7

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(38, 12) = 228

GCD(38, 12) = ( 38 x 12 ) / 228

GCD(38, 12) = 456 / 228

GCD(38, 12) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 49

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

LCM(2, 49) = 98

GCD(2, 49) = ( 2 x 49 ) / 98

GCD(2, 49) = 98 / 98

GCD(2, 49) = 1

GCD of 38, 12, 49 is 1
