We found the divisors of 670, 821, 95, 196 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 670, 821, 95, 196 is 1.

Therefore, GCD of numbers 670, 821, 95, 196 is 1

Given Input Data is 670, 821, 95, 196

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

Prime Factorization of 670 is 2 x 5 x 67

Prime Factorization of 821 is 821

Prime Factorization of 95 is 5 x 19

Prime Factorization of 196 is 2 x 2 x 7 x 7

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(670, 821) = 550070

GCD(670, 821) = ( 670 x 821 ) / 550070

GCD(670, 821) = 550070 / 550070

GCD(670, 821) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 95

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

LCM(1, 95) = 95

GCD(1, 95) = ( 1 x 95 ) / 95

GCD(1, 95) = 95 / 95

GCD(1, 95) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 196

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

LCM(1, 196) = 196

GCD(1, 196) = ( 1 x 196 ) / 196

GCD(1, 196) = 196 / 196

GCD(1, 196) = 1

GCD of 670, 821, 95, 196 is 1
