Therefore, GCD of numbers 810, 875, 77 is 1

Given Input Data is 810, 875, 77

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

Prime Factorization of 810 is 2 x 3 x 3 x 3 x 3 x 5

Prime Factorization of 875 is 5 x 5 x 5 x 7

Prime Factorization of 77 is 7 x 11

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(810, 875) = 141750

GCD(810, 875) = ( 810 x 875 ) / 141750

GCD(810, 875) = 708750 / 141750

GCD(810, 875) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 77

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

LCM(5, 77) = 385

GCD(5, 77) = ( 5 x 77 ) / 385

GCD(5, 77) = 385 / 385

GCD(5, 77) = 1

GCD of 810, 875, 77 is 1
