Therefore, GCD of numbers 70, 676, 155, 485 is 1

Given Input Data is 70, 676, 155, 485

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 676 is 2 x 2 x 13 x 13

Prime Factorization of 155 is 5 x 31

Prime Factorization of 485 is 5 x 97

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, 676) = 23660

GCD(70, 676) = ( 70 x 676 ) / 23660

GCD(70, 676) = 47320 / 23660

GCD(70, 676) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 155

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

LCM(2, 155) = 310

GCD(2, 155) = ( 2 x 155 ) / 310

GCD(2, 155) = 310 / 310

GCD(2, 155) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 485

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

LCM(1, 485) = 485

GCD(1, 485) = ( 1 x 485 ) / 485

GCD(1, 485) = 485 / 485

GCD(1, 485) = 1

GCD of 70, 676, 155, 485 is 1
