Therefore, GCD of numbers 763, 847, 51, 778 is 1

Given Input Data is 763, 847, 51, 778

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

Prime Factorization of 763 is 7 x 109

Prime Factorization of 847 is 7 x 11 x 11

Prime Factorization of 51 is 3 x 17

Prime Factorization of 778 is 2 x 389

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(763, 847) = 92323

GCD(763, 847) = ( 763 x 847 ) / 92323

GCD(763, 847) = 646261 / 92323

GCD(763, 847) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 51

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

LCM(7, 51) = 357

GCD(7, 51) = ( 7 x 51 ) / 357

GCD(7, 51) = 357 / 357

GCD(7, 51) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 778

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

LCM(1, 778) = 778

GCD(1, 778) = ( 1 x 778 ) / 778

GCD(1, 778) = 778 / 778

GCD(1, 778) = 1

GCD of 763, 847, 51, 778 is 1
