We found the divisors of 385, 421, 33, 722 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 385, 421, 33, 722 is 1.

Therefore, GCD of numbers 385, 421, 33, 722 is 1

Given Input Data is 385, 421, 33, 722

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

Prime Factorization of 385 is 5 x 7 x 11

Prime Factorization of 421 is 421

Prime Factorization of 33 is 3 x 11

Prime Factorization of 722 is 2 x 19 x 19

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(385, 421) = 162085

GCD(385, 421) = ( 385 x 421 ) / 162085

GCD(385, 421) = 162085 / 162085

GCD(385, 421) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 33

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

LCM(1, 33) = 33

GCD(1, 33) = ( 1 x 33 ) / 33

GCD(1, 33) = 33 / 33

GCD(1, 33) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 722

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

LCM(1, 722) = 722

GCD(1, 722) = ( 1 x 722 ) / 722

GCD(1, 722) = 722 / 722

GCD(1, 722) = 1

GCD of 385, 421, 33, 722 is 1
