Therefore, GCD of numbers 91, 924, 219, 455 is 1

Given Input Data is 91, 924, 219, 455

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

Prime Factorization of 91 is 7 x 13

Prime Factorization of 924 is 2 x 2 x 3 x 7 x 11

Prime Factorization of 219 is 3 x 73

Prime Factorization of 455 is 5 x 7 x 13

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(91, 924) = 12012

GCD(91, 924) = ( 91 x 924 ) / 12012

GCD(91, 924) = 84084 / 12012

GCD(91, 924) = 7

Step2:

Here we consider the GCD from the above i.e. 7 as first number and the next as 219

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

LCM(7, 219) = 1533

GCD(7, 219) = ( 7 x 219 ) / 1533

GCD(7, 219) = 1533 / 1533

GCD(7, 219) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 455

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

LCM(1, 455) = 455

GCD(1, 455) = ( 1 x 455 ) / 455

GCD(1, 455) = 455 / 455

GCD(1, 455) = 1

GCD of 91, 924, 219, 455 is 1
