Therefore, GCD of numbers 625, 385, 64, 561 is 1

Given Input Data is 625, 385, 64, 561

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

Prime Factorization of 625 is 5 x 5 x 5 x 5

Prime Factorization of 385 is 5 x 7 x 11

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

Prime Factorization of 561 is 3 x 11 x 17

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(625, 385) = 48125

GCD(625, 385) = ( 625 x 385 ) / 48125

GCD(625, 385) = 240625 / 48125

GCD(625, 385) = 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 561

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

LCM(1, 561) = 561

GCD(1, 561) = ( 1 x 561 ) / 561

GCD(1, 561) = 561 / 561

GCD(1, 561) = 1

GCD of 625, 385, 64, 561 is 1
