We found the divisors of 651, 662, 27, 670 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 651, 662, 27, 670 is 1.

Therefore, GCD of numbers 651, 662, 27, 670 is 1

Given Input Data is 651, 662, 27, 670

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

Prime Factorization of 651 is 3 x 7 x 31

Prime Factorization of 662 is 2 x 331

Prime Factorization of 27 is 3 x 3 x 3

Prime Factorization of 670 is 2 x 5 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(651, 662) = 430962

GCD(651, 662) = ( 651 x 662 ) / 430962

GCD(651, 662) = 430962 / 430962

GCD(651, 662) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 27

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

LCM(1, 27) = 27

GCD(1, 27) = ( 1 x 27 ) / 27

GCD(1, 27) = 27 / 27

GCD(1, 27) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 670

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

LCM(1, 670) = 670

GCD(1, 670) = ( 1 x 670 ) / 670

GCD(1, 670) = 670 / 670

GCD(1, 670) = 1

GCD of 651, 662, 27, 670 is 1
