Therefore, GCD of numbers 141, 921, 280, 863 is 1

Given Input Data is 141, 921, 280, 863

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

Prime Factorization of 141 is 3 x 47

Prime Factorization of 921 is 3 x 307

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

Prime Factorization of 863 is 863

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(141, 921) = 43287

GCD(141, 921) = ( 141 x 921 ) / 43287

GCD(141, 921) = 129861 / 43287

GCD(141, 921) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 280

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

LCM(3, 280) = 840

GCD(3, 280) = ( 3 x 280 ) / 840

GCD(3, 280) = 840 / 840

GCD(3, 280) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 863

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

LCM(1, 863) = 863

GCD(1, 863) = ( 1 x 863 ) / 863

GCD(1, 863) = 863 / 863

GCD(1, 863) = 1

GCD of 141, 921, 280, 863 is 1
