We found the divisors of 814, 771, 15, 711 . The biggest common divisior number is the GCD number.
So the Greatest Common Divisior 814, 771, 15, 711 is 1.

Therefore, GCD of numbers 814, 771, 15, 711 is 1

Given Input Data is 814, 771, 15, 711

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

Prime Factorization of 814 is 2 x 11 x 37

Prime Factorization of 771 is 3 x 257

Prime Factorization of 15 is 3 x 5

Prime Factorization of 711 is 3 x 3 x 79

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(814, 771) = 627594

GCD(814, 771) = ( 814 x 771 ) / 627594

GCD(814, 771) = 627594 / 627594

GCD(814, 771) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 15

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

LCM(1, 15) = 15

GCD(1, 15) = ( 1 x 15 ) / 15

GCD(1, 15) = 15 / 15

GCD(1, 15) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 711

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

LCM(1, 711) = 711

GCD(1, 711) = ( 1 x 711 ) / 711

GCD(1, 711) = 711 / 711

GCD(1, 711) = 1

GCD of 814, 771, 15, 711 is 1
