Therefore, GCD of numbers 768, 831, 785, 651 is 1

Given Input Data is 768, 831, 785, 651

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

Prime Factorization of 768 is 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 x 3

Prime Factorization of 831 is 3 x 277

Prime Factorization of 785 is 5 x 157

Prime Factorization of 651 is 3 x 7 x 31

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(768, 831) = 212736

GCD(768, 831) = ( 768 x 831 ) / 212736

GCD(768, 831) = 638208 / 212736

GCD(768, 831) = 3

Step2:

Here we consider the GCD from the above i.e. 3 as first number and the next as 785

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

LCM(3, 785) = 2355

GCD(3, 785) = ( 3 x 785 ) / 2355

GCD(3, 785) = 2355 / 2355

GCD(3, 785) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 651

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

LCM(1, 651) = 651

GCD(1, 651) = ( 1 x 651 ) / 651

GCD(1, 651) = 651 / 651

GCD(1, 651) = 1

GCD of 768, 831, 785, 651 is 1
