Therefore, GCD of numbers 14, 245, 145, 971 is 1

Given Input Data is 14, 245, 145, 971

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

Prime Factorization of 14 is 2 x 7

Prime Factorization of 245 is 5 x 7 x 7

Prime Factorization of 145 is 5 x 29

Prime Factorization of 971 is 971

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(14, 245) = 490

GCD(14, 245) = ( 14 x 245 ) / 490

GCD(14, 245) = 3430 / 490

GCD(14, 245) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 145

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

LCM(7, 145) = 1015

GCD(7, 145) = ( 7 x 145 ) / 1015

GCD(7, 145) = 1015 / 1015

GCD(7, 145) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 971

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

LCM(1, 971) = 971

GCD(1, 971) = ( 1 x 971 ) / 971

GCD(1, 971) = 971 / 971

GCD(1, 971) = 1

GCD of 14, 245, 145, 971 is 1
