Given Input Data is 195, 755, 860, 427

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

Prime Factorization of 195 is 3 x 5 x 13

Prime Factorization of 755 is 5 x 151

Prime Factorization of 860 is 2 x 2 x 5 x 43

Prime Factorization of 427 is 7 x 61

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(195, 755) = 29445

GCD(195, 755) = ( 195 x 755 ) / 29445

GCD(195, 755) = 147225 / 29445

GCD(195, 755) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 860

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

LCM(5, 860) = 860

GCD(5, 860) = ( 5 x 860 ) / 860

GCD(5, 860) = 4300 / 860

GCD(5, 860) = 5

Step3:

Here we consider the GCD from the above i.e. 5 as first number and the next as 427

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

LCM(5, 427) = 2135

GCD(5, 427) = ( 5 x 427 ) / 2135

GCD(5, 427) = 2135 / 2135

GCD(5, 427) = 1

GCD of 195, 755, 860, 427 is 1
