Therefore, GCD of numbers 30, 624, 419, 625 is 1

Given Input Data is 30, 624, 419, 625

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

Prime Factorization of 30 is 2 x 3 x 5

Prime Factorization of 624 is 2 x 2 x 2 x 2 x 3 x 13

Prime Factorization of 419 is 419

Prime Factorization of 625 is 5 x 5 x 5 x 5

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(30, 624) = 3120

GCD(30, 624) = ( 30 x 624 ) / 3120

GCD(30, 624) = 18720 / 3120

GCD(30, 624) = 6

Step2:

Here we consider the GCD from the above i.e. 6 as first number and the next as 419

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

LCM(6, 419) = 2514

GCD(6, 419) = ( 6 x 419 ) / 2514

GCD(6, 419) = 2514 / 2514

GCD(6, 419) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 625

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

LCM(1, 625) = 625

GCD(1, 625) = ( 1 x 625 ) / 625

GCD(1, 625) = 625 / 625

GCD(1, 625) = 1

GCD of 30, 624, 419, 625 is 1
