We found the divisors of 38, 77, 85, 45 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 38, 77, 85, 45 is 1.

Therefore, GCD of numbers 38, 77, 85, 45 is 1

Given Input Data is 38, 77, 85, 45

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

Prime Factorization of 38 is 2 x 19

Prime Factorization of 77 is 7 x 11

Prime Factorization of 85 is 5 x 17

Prime Factorization of 45 is 3 x 3 x 5

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, 77) = 2926

GCD(38, 77) = ( 38 x 77 ) / 2926

GCD(38, 77) = 2926 / 2926

GCD(38, 77) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 85

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

LCM(1, 85) = 85

GCD(1, 85) = ( 1 x 85 ) / 85

GCD(1, 85) = 85 / 85

GCD(1, 85) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 45

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

LCM(1, 45) = 45

GCD(1, 45) = ( 1 x 45 ) / 45

GCD(1, 45) = 45 / 45

GCD(1, 45) = 1

GCD of 38, 77, 85, 45 is 1
