Given Input Data is 124, 713, 503, 920

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

Prime Factorization of 124 is 2 x 2 x 31

Prime Factorization of 713 is 23 x 31

Prime Factorization of 503 is 503

Prime Factorization of 920 is 2 x 2 x 2 x 5 x 23

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(124, 713) = 2852

GCD(124, 713) = ( 124 x 713 ) / 2852

GCD(124, 713) = 88412 / 2852

GCD(124, 713) = 31

Step2:

Here we consider the GCD from the above i.e. 31 as first number and the next as 503

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

LCM(31, 503) = 15593

GCD(31, 503) = ( 31 x 503 ) / 15593

GCD(31, 503) = 15593 / 15593

GCD(31, 503) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 920

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

LCM(1, 920) = 920

GCD(1, 920) = ( 1 x 920 ) / 920

GCD(1, 920) = 920 / 920

GCD(1, 920) = 1

GCD of 124, 713, 503, 920 is 1
