We found the divisors of 57, 47, 81, 35 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 57, 47, 81, 35 is 1.

Therefore, GCD of numbers 57, 47, 81, 35 is 1

Given Input Data is 57, 47, 81, 35

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

Prime Factorization of 57 is 3 x 19

Prime Factorization of 47 is 47

Prime Factorization of 81 is 3 x 3 x 3 x 3

Prime Factorization of 35 is 5 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(57, 47) = 2679

GCD(57, 47) = ( 57 x 47 ) / 2679

GCD(57, 47) = 2679 / 2679

GCD(57, 47) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 81

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

LCM(1, 81) = 81

GCD(1, 81) = ( 1 x 81 ) / 81

GCD(1, 81) = 81 / 81

GCD(1, 81) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 35

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

LCM(1, 35) = 35

GCD(1, 35) = ( 1 x 35 ) / 35

GCD(1, 35) = 35 / 35

GCD(1, 35) = 1

GCD of 57, 47, 81, 35 is 1
