Therefore, GCD of numbers 74, 640, 263, 723 is 1

Given Input Data is 74, 640, 263, 723

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

Prime Factorization of 74 is 2 x 37

Prime Factorization of 640 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime Factorization of 263 is 263

Prime Factorization of 723 is 3 x 241

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(74, 640) = 23680

GCD(74, 640) = ( 74 x 640 ) / 23680

GCD(74, 640) = 47360 / 23680

GCD(74, 640) = 2

Step2:

Here we consider the GCD from the above i.e. 2 as first number and the next as 263

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

LCM(2, 263) = 526

GCD(2, 263) = ( 2 x 263 ) / 526

GCD(2, 263) = 526 / 526

GCD(2, 263) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 723

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

LCM(1, 723) = 723

GCD(1, 723) = ( 1 x 723 ) / 723

GCD(1, 723) = 723 / 723

GCD(1, 723) = 1

GCD of 74, 640, 263, 723 is 1
