Greatest Common Divisior

We found the divisors of 70, 127, 690, 641 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 70, 127, 690, 641 is 1.

Therefore, GCD of numbers 70, 127, 690, 641 is 1

Given Input Data is 70, 127, 690, 641

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

Prime Factorization of 70 is 2 x 5 x 7

Prime Factorization of 127 is 127

Prime Factorization of 690 is 2 x 3 x 5 x 23

Prime Factorization of 641 is 641

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(70, 127) = 8890

GCD(70, 127) = ( 70 x 127 ) / 8890

GCD(70, 127) = 8890 / 8890

GCD(70, 127) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 690

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

LCM(1, 690) = 690

GCD(1, 690) = ( 1 x 690 ) / 690

GCD(1, 690) = 690 / 690

GCD(1, 690) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 641

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

LCM(1, 641) = 641

GCD(1, 641) = ( 1 x 641 ) / 641

GCD(1, 641) = 641 / 641

GCD(1, 641) = 1

GCD of 70, 127, 690, 641 is 1
