We found the divisors of 402, 403, 37, 978 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 402, 403, 37, 978 is 1.

Therefore, GCD of numbers 402, 403, 37, 978 is 1

Given Input Data is 402, 403, 37, 978

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

Prime Factorization of 402 is 2 x 3 x 67

Prime Factorization of 403 is 13 x 31

Prime Factorization of 37 is 37

Prime Factorization of 978 is 2 x 3 x 163

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(402, 403) = 162006

GCD(402, 403) = ( 402 x 403 ) / 162006

GCD(402, 403) = 162006 / 162006

GCD(402, 403) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 37

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

LCM(1, 37) = 37

GCD(1, 37) = ( 1 x 37 ) / 37

GCD(1, 37) = 37 / 37

GCD(1, 37) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 978

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

LCM(1, 978) = 978

GCD(1, 978) = ( 1 x 978 ) / 978

GCD(1, 978) = 978 / 978

GCD(1, 978) = 1

GCD of 402, 403, 37, 978 is 1
