We found the divisors of 38, 55, 83, 66 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 38, 55, 83, 66 is 1.

Therefore, GCD of numbers 38, 55, 83, 66 is 1

Given Input Data is 38, 55, 83, 66

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

Prime Factorization of 38 is 2 x 19

Prime Factorization of 55 is 5 x 11

Prime Factorization of 83 is 83

Prime Factorization of 66 is 2 x 3 x 11

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, 55) = 2090

GCD(38, 55) = ( 38 x 55 ) / 2090

GCD(38, 55) = 2090 / 2090

GCD(38, 55) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 83

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

LCM(1, 83) = 83

GCD(1, 83) = ( 1 x 83 ) / 83

GCD(1, 83) = 83 / 83

GCD(1, 83) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 66

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

LCM(1, 66) = 66

GCD(1, 66) = ( 1 x 66 ) / 66

GCD(1, 66) = 66 / 66

GCD(1, 66) = 1

GCD of 38, 55, 83, 66 is 1
