Therefore, GCD of numbers 968, 280, 107, 861 is 1

Given Input Data is 968, 280, 107, 861

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

Prime Factorization of 968 is 2 x 2 x 2 x 11 x 11

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

Prime Factorization of 107 is 107

Prime Factorization of 861 is 3 x 7 x 41

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(968, 280) = 33880

GCD(968, 280) = ( 968 x 280 ) / 33880

GCD(968, 280) = 271040 / 33880

GCD(968, 280) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 107

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

LCM(8, 107) = 856

GCD(8, 107) = ( 8 x 107 ) / 856

GCD(8, 107) = 856 / 856

GCD(8, 107) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 861

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

LCM(1, 861) = 861

GCD(1, 861) = ( 1 x 861 ) / 861

GCD(1, 861) = 861 / 861

GCD(1, 861) = 1

GCD of 968, 280, 107, 861 is 1
