Therefore, GCD of numbers 306, 186, 22, 493 is 1

Given Input Data is 306, 186, 22, 493

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

Prime Factorization of 306 is 2 x 3 x 3 x 17

Prime Factorization of 186 is 2 x 3 x 31

Prime Factorization of 22 is 2 x 11

Prime Factorization of 493 is 17 x 29

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(306, 186) = 9486

GCD(306, 186) = ( 306 x 186 ) / 9486

GCD(306, 186) = 56916 / 9486

GCD(306, 186) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 22

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

LCM(6, 22) = 66

GCD(6, 22) = ( 6 x 22 ) / 66

GCD(6, 22) = 132 / 66

GCD(6, 22) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 493

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

LCM(2, 493) = 986

GCD(2, 493) = ( 2 x 493 ) / 986

GCD(2, 493) = 986 / 986

GCD(2, 493) = 1

GCD of 306, 186, 22, 493 is 1
