Therefore, GCD of numbers 325, 245, 64, 693 is 1

Given Input Data is 325, 245, 64, 693

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

Prime Factorization of 325 is 5 x 5 x 13

Prime Factorization of 245 is 5 x 7 x 7

Prime Factorization of 64 is 2 x 2 x 2 x 2 x 2 x 2

Prime Factorization of 693 is 3 x 3 x 7 x 11

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(325, 245) = 15925

GCD(325, 245) = ( 325 x 245 ) / 15925

GCD(325, 245) = 79625 / 15925

GCD(325, 245) = 5

Step2:

Here we consider the GCD from the above i.e. 5 as first number and the next as 64

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

LCM(5, 64) = 320

GCD(5, 64) = ( 5 x 64 ) / 320

GCD(5, 64) = 320 / 320

GCD(5, 64) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 693

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

LCM(1, 693) = 693

GCD(1, 693) = ( 1 x 693 ) / 693

GCD(1, 693) = 693 / 693

GCD(1, 693) = 1

GCD of 325, 245, 64, 693 is 1
