Therefore, GCD of numbers 390, 477, 427 is 1

Given Input Data is 390, 477, 427

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

Prime Factorization of 390 is 2 x 3 x 5 x 13

Prime Factorization of 477 is 3 x 3 x 53

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(390, 477) = 62010

GCD(390, 477) = ( 390 x 477 ) / 62010

GCD(390, 477) = 186030 / 62010

GCD(390, 477) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 427

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

LCM(3, 427) = 1281

GCD(3, 427) = ( 3 x 427 ) / 1281

GCD(3, 427) = 1281 / 1281

GCD(3, 427) = 1

GCD of 390, 477, 427 is 1
