Therefore, GCD of numbers 454, 908, 691, 987 is 1

Given Input Data is 454, 908, 691, 987

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

Prime Factorization of 454 is 2 x 227

Prime Factorization of 908 is 2 x 2 x 227

Prime Factorization of 691 is 691

Prime Factorization of 987 is 3 x 7 x 47

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(454, 908) = 908

GCD(454, 908) = ( 454 x 908 ) / 908

GCD(454, 908) = 412232 / 908

GCD(454, 908) = 454

Step2:

Here we consider the GCD from the above i.e. 454 as first number and the next as 691

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

LCM(454, 691) = 313714

GCD(454, 691) = ( 454 x 691 ) / 313714

GCD(454, 691) = 313714 / 313714

GCD(454, 691) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 987

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

LCM(1, 987) = 987

GCD(1, 987) = ( 1 x 987 ) / 987

GCD(1, 987) = 987 / 987

GCD(1, 987) = 1

GCD of 454, 908, 691, 987 is 1
