Given Input Data is 393, 402, 476

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

Prime Factorization of 393 is 3 x 131

Prime Factorization of 402 is 2 x 3 x 67

Prime Factorization of 476 is 2 x 2 x 7 x 17

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(393, 402) = 52662

GCD(393, 402) = ( 393 x 402 ) / 52662

GCD(393, 402) = 157986 / 52662

GCD(393, 402) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 476

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

LCM(3, 476) = 1428

GCD(3, 476) = ( 3 x 476 ) / 1428

GCD(3, 476) = 1428 / 1428

GCD(3, 476) = 1

GCD of 393, 402, 476 is 1
