Therefore, GCD of numbers 869, 726, 45, 215 is 1

Given Input Data is 869, 726, 45, 215

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

Prime Factorization of 869 is 11 x 79

Prime Factorization of 726 is 2 x 3 x 11 x 11

Prime Factorization of 45 is 3 x 3 x 5

Prime Factorization of 215 is 5 x 43

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(869, 726) = 57354

GCD(869, 726) = ( 869 x 726 ) / 57354

GCD(869, 726) = 630894 / 57354

GCD(869, 726) = 11

Step2:

Here we consider the GCD from the above i.e. 11 as first number and the next as 45

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

LCM(11, 45) = 495

GCD(11, 45) = ( 11 x 45 ) / 495

GCD(11, 45) = 495 / 495

GCD(11, 45) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 215

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

LCM(1, 215) = 215

GCD(1, 215) = ( 1 x 215 ) / 215

GCD(1, 215) = 215 / 215

GCD(1, 215) = 1

GCD of 869, 726, 45, 215 is 1
