Given Input Data is 861, 540, 941, 115

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

Prime Factorization of 861 is 3 x 7 x 41

Prime Factorization of 540 is 2 x 2 x 3 x 3 x 3 x 5

Prime Factorization of 941 is 941

Prime Factorization of 115 is 5 x 23

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(861, 540) = 154980

GCD(861, 540) = ( 861 x 540 ) / 154980

GCD(861, 540) = 464940 / 154980

GCD(861, 540) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 941

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

LCM(3, 941) = 2823

GCD(3, 941) = ( 3 x 941 ) / 2823

GCD(3, 941) = 2823 / 2823

GCD(3, 941) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 115

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

LCM(1, 115) = 115

GCD(1, 115) = ( 1 x 115 ) / 115

GCD(1, 115) = 115 / 115

GCD(1, 115) = 1

GCD of 861, 540, 941, 115 is 1
