So the Greatest Common Divisior 853, 856, 615, 765 is 1.

Therefore, GCD of numbers 853, 856, 615, 765 is 1

Given Input Data is 853, 856, 615, 765

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

Prime Factorization of 853 is 853

Prime Factorization of 856 is 2 x 2 x 2 x 107

Prime Factorization of 615 is 3 x 5 x 41

Prime Factorization of 765 is 3 x 3 x 5 x 17

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(853, 856) = 730168

GCD(853, 856) = ( 853 x 856 ) / 730168

GCD(853, 856) = 730168 / 730168

GCD(853, 856) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 615

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

LCM(1, 615) = 615

GCD(1, 615) = ( 1 x 615 ) / 615

GCD(1, 615) = 615 / 615

GCD(1, 615) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 765

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

LCM(1, 765) = 765

GCD(1, 765) = ( 1 x 765 ) / 765

GCD(1, 765) = 765 / 765

GCD(1, 765) = 1

GCD of 853, 856, 615, 765 is 1
