Therefore, GCD of numbers 320, 632, 82, 243 is 1

Given Input Data is 320, 632, 82, 243

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

Prime Factorization of 320 is 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime Factorization of 632 is 2 x 2 x 2 x 79

Prime Factorization of 82 is 2 x 41

Prime Factorization of 243 is 3 x 3 x 3 x 3 x 3

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(320, 632) = 25280

GCD(320, 632) = ( 320 x 632 ) / 25280

GCD(320, 632) = 202240 / 25280

GCD(320, 632) = 8

Step2:

Here we consider the GCD from the above i.e. 8 as first number and the next as 82

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

LCM(8, 82) = 328

GCD(8, 82) = ( 8 x 82 ) / 328

GCD(8, 82) = 656 / 328

GCD(8, 82) = 2

Step3:

Here we consider the GCD from the above i.e. 2 as first number and the next as 243

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

LCM(2, 243) = 486

GCD(2, 243) = ( 2 x 243 ) / 486

GCD(2, 243) = 486 / 486

GCD(2, 243) = 1

GCD of 320, 632, 82, 243 is 1
