Therefore, GCD of numbers 306, 219, 63, 857 is 1

Given Input Data is 306, 219, 63, 857

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 219 is 3 x 73

Prime Factorization of 63 is 3 x 3 x 7

Prime Factorization of 857 is 857

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, 219) = 22338

GCD(306, 219) = ( 306 x 219 ) / 22338

GCD(306, 219) = 67014 / 22338

GCD(306, 219) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 63

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

LCM(3, 63) = 63

GCD(3, 63) = ( 3 x 63 ) / 63

GCD(3, 63) = 189 / 63

GCD(3, 63) = 3

Step3:

Here we consider the GCD from the above i.e. 3 as first number and the next as 857

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

LCM(3, 857) = 2571

GCD(3, 857) = ( 3 x 857 ) / 2571

GCD(3, 857) = 2571 / 2571

GCD(3, 857) = 1

GCD of 306, 219, 63, 857 is 1
