We found the divisors of 424, 503, 402 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 424, 503, 402 is 1.

Therefore, GCD of numbers 424, 503, 402 is 1

Given Input Data is 424, 503, 402

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

Prime Factorization of 424 is 2 x 2 x 2 x 53

Prime Factorization of 503 is 503

Prime Factorization of 402 is 2 x 3 x 67

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(424, 503) = 213272

GCD(424, 503) = ( 424 x 503 ) / 213272

GCD(424, 503) = 213272 / 213272

GCD(424, 503) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 402

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

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

GCD(1, 402) = 402 / 402

GCD(1, 402) = 1

GCD of 424, 503, 402 is 1
