So the Greatest Common Divisior 381, 747, 406, 737 is 1.

Therefore, GCD of numbers 381, 747, 406, 737 is 1

Given Input Data is 381, 747, 406, 737

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

Prime Factorization of 381 is 3 x 127

Prime Factorization of 747 is 3 x 3 x 83

Prime Factorization of 406 is 2 x 7 x 29

Prime Factorization of 737 is 11 x 67

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(381, 747) = 94869

GCD(381, 747) = ( 381 x 747 ) / 94869

GCD(381, 747) = 284607 / 94869

GCD(381, 747) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 406

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

LCM(3, 406) = 1218

GCD(3, 406) = ( 3 x 406 ) / 1218

GCD(3, 406) = 1218 / 1218

GCD(3, 406) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 737

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

LCM(1, 737) = 737

GCD(1, 737) = ( 1 x 737 ) / 737

GCD(1, 737) = 737 / 737

GCD(1, 737) = 1

GCD of 381, 747, 406, 737 is 1
