Therefore, GCD of numbers 280, 661, 482, 979 is 1

Given Input Data is 280, 661, 482, 979

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

Prime Factorization of 280 is 2 x 2 x 2 x 5 x 7

Prime Factorization of 661 is 661

Prime Factorization of 482 is 2 x 241

Prime Factorization of 979 is 11 x 89

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(280, 661) = 185080

GCD(280, 661) = ( 280 x 661 ) / 185080

GCD(280, 661) = 185080 / 185080

GCD(280, 661) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 482

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

LCM(1, 482) = 482

GCD(1, 482) = ( 1 x 482 ) / 482

GCD(1, 482) = 482 / 482

GCD(1, 482) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 979

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

LCM(1, 979) = 979

GCD(1, 979) = ( 1 x 979 ) / 979

GCD(1, 979) = 979 / 979

GCD(1, 979) = 1

GCD of 280, 661, 482, 979 is 1
