We found the divisors of 19, 251, 770, 878 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 19, 251, 770, 878 is 1.

Therefore, GCD of numbers 19, 251, 770, 878 is 1

Given Input Data is 19, 251, 770, 878

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

Prime Factorization of 19 is 19

Prime Factorization of 251 is 251

Prime Factorization of 770 is 2 x 5 x 7 x 11

Prime Factorization of 878 is 2 x 439

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(19, 251) = 4769

GCD(19, 251) = ( 19 x 251 ) / 4769

GCD(19, 251) = 4769 / 4769

GCD(19, 251) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 770

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

LCM(1, 770) = 770

GCD(1, 770) = ( 1 x 770 ) / 770

GCD(1, 770) = 770 / 770

GCD(1, 770) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 878

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

LCM(1, 878) = 878

GCD(1, 878) = ( 1 x 878 ) / 878

GCD(1, 878) = 878 / 878

GCD(1, 878) = 1

GCD of 19, 251, 770, 878 is 1
