Therefore, GCD of numbers 670, 660, 95, 171 is 1

Given Input Data is 670, 660, 95, 171

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 660 is 2 x 2 x 3 x 5 x 11

Prime Factorization of 95 is 5 x 19

Prime Factorization of 171 is 3 x 3 x 19

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, 660) = 44220

GCD(670, 660) = ( 670 x 660 ) / 44220

GCD(670, 660) = 442200 / 44220

GCD(670, 660) = 10

Step2:

Here we consider the GCD from the above i.e. 10 as first number and the next as 95

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

LCM(10, 95) = 190

GCD(10, 95) = ( 10 x 95 ) / 190

GCD(10, 95) = 950 / 190

GCD(10, 95) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 171

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

LCM(5, 171) = 855

GCD(5, 171) = ( 5 x 171 ) / 855

GCD(5, 171) = 855 / 855

GCD(5, 171) = 1

GCD of 670, 660, 95, 171 is 1
