Given Input Data is 721, 920, 888, 907

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

Prime Factorization of 721 is 7 x 103

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

Prime Factorization of 888 is 2 x 2 x 2 x 3 x 37

Prime Factorization of 907 is 907

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(721, 920) = 663320

GCD(721, 920) = ( 721 x 920 ) / 663320

GCD(721, 920) = 663320 / 663320

GCD(721, 920) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 888

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

LCM(1, 888) = 888

GCD(1, 888) = ( 1 x 888 ) / 888

GCD(1, 888) = 888 / 888

GCD(1, 888) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 907

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

LCM(1, 907) = 907

GCD(1, 907) = ( 1 x 907 ) / 907

GCD(1, 907) = 907 / 907

GCD(1, 907) = 1

GCD of 721, 920, 888, 907 is 1
