We found the divisors of 645, 737, 26, 406 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 645, 737, 26, 406 is 1.

Therefore, GCD of numbers 645, 737, 26, 406 is 1

Given Input Data is 645, 737, 26, 406

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

Prime Factorization of 645 is 3 x 5 x 43

Prime Factorization of 737 is 11 x 67

Prime Factorization of 26 is 2 x 13

Prime Factorization of 406 is 2 x 7 x 29

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(645, 737) = 475365

GCD(645, 737) = ( 645 x 737 ) / 475365

GCD(645, 737) = 475365 / 475365

GCD(645, 737) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 26

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

LCM(1, 26) = 26

GCD(1, 26) = ( 1 x 26 ) / 26

GCD(1, 26) = 26 / 26

GCD(1, 26) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 406

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

LCM(1, 406) = 406

GCD(1, 406) = ( 1 x 406 ) / 406

GCD(1, 406) = 406 / 406

GCD(1, 406) = 1

GCD of 645, 737, 26, 406 is 1
