Therefore, GCD of numbers 715, 555, 381, 787 is 1

Given Input Data is 715, 555, 381, 787

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

Prime Factorization of 715 is 5 x 11 x 13

Prime Factorization of 555 is 3 x 5 x 37

Prime Factorization of 381 is 3 x 127

Prime Factorization of 787 is 787

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(715, 555) = 79365

GCD(715, 555) = ( 715 x 555 ) / 79365

GCD(715, 555) = 396825 / 79365

GCD(715, 555) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 381

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

LCM(5, 381) = 1905

GCD(5, 381) = ( 5 x 381 ) / 1905

GCD(5, 381) = 1905 / 1905

GCD(5, 381) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 787

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

LCM(1, 787) = 787

GCD(1, 787) = ( 1 x 787 ) / 787

GCD(1, 787) = 787 / 787

GCD(1, 787) = 1

GCD of 715, 555, 381, 787 is 1
