We found the divisors of 33, 181, 642, 407 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 33, 181, 642, 407 is 1.

Therefore, GCD of numbers 33, 181, 642, 407 is 1

Given Input Data is 33, 181, 642, 407

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

Prime Factorization of 33 is 3 x 11

Prime Factorization of 181 is 181

Prime Factorization of 642 is 2 x 3 x 107

Prime Factorization of 407 is 11 x 37

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(33, 181) = 5973

GCD(33, 181) = ( 33 x 181 ) / 5973

GCD(33, 181) = 5973 / 5973

GCD(33, 181) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 642

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

LCM(1, 642) = 642

GCD(1, 642) = ( 1 x 642 ) / 642

GCD(1, 642) = 642 / 642

GCD(1, 642) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 407

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

LCM(1, 407) = 407

GCD(1, 407) = ( 1 x 407 ) / 407

GCD(1, 407) = 407 / 407

GCD(1, 407) = 1

GCD of 33, 181, 642, 407 is 1
