Therefore, GCD of numbers 210, 217, 68, 624 is 1

Given Input Data is 210, 217, 68, 624

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

Prime Factorization of 210 is 2 x 3 x 5 x 7

Prime Factorization of 217 is 7 x 31

Prime Factorization of 68 is 2 x 2 x 17

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

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(210, 217) = 6510

GCD(210, 217) = ( 210 x 217 ) / 6510

GCD(210, 217) = 45570 / 6510

GCD(210, 217) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 68

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

LCM(7, 68) = 476

GCD(7, 68) = ( 7 x 68 ) / 476

GCD(7, 68) = 476 / 476

GCD(7, 68) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 624

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

LCM(1, 624) = 624

GCD(1, 624) = ( 1 x 624 ) / 624

GCD(1, 624) = 624 / 624

GCD(1, 624) = 1

GCD of 210, 217, 68, 624 is 1
